Description Earlier this year NXP organized a promotional opportunity for amateur radio enthusiasts to use their creativity and build their own power amplifier designs. NXP received numerous creative submissions in this competitive Homebrew RF Design Challenge. We appreciate the dedication and enthusiasm from the community that made this contest a success. First place winner An MRF101AN broadband amplifier design with 1 W Input, 100 W Output 1.8-54 MHZ Amplifier deck. (For more information visit:NXP MRF-101 - RFPowerTools )  It is an amplifier with a bandwidth of 1.8MHz to 54MHz. Maximum output power of 100W up to 30MHz and 70W up to 50MHz. Maximum power supply 50V to 4A, with a Voltage Standing Wave Ratio of 1.5:1 maximum. The design dimensions of the PCB is 5x5 cm (2x2 in). and 310g weight including fan and heat sink. Second place winner A 600W broadband HF amplifier using affordable LDMOS devices (For more information visit: https://qrpblog.com/2019/10/a-600w-broadband-hf-amplifier-using-affordable-ldmos-devices/  ) This project is meant to demonstrate the capabilities of the MRF300 transistors as linear broadband devices in the 2-50MHz range and to be used by radio amateurs as a starting point for a medium-high power amplifier. This is also my entry to the NXP Homebrew RF Design Challenge 2019. To achieve the target of 600W output while also minimizing the level of even-number harmonics, a “push-pull” configuration of two transistors is used. Luckily, the manufacturer made it easy to design the PCB layout for such a thing by offering two versions (the MRF300AN & MRF300BN) that have mirrored pinout. The common TO-247 package is used, with the source connected to the tab. Each individual MRF300 LDMOS transistor is specified at 330W output over a 1.8-250MHz working frequency range, a maximum 28dB of gain and over 70% efficiency. The recommended supply range is 30-50Vdc. By studying the specifications, it looks like with correct broadband matching and some operational safety margin we can get close to 600W output at a voltage of around 45V across a resonably large bandwidth; the aim is to cover 1.8 to 54MHz. Main challenges when designing this amplifier are related to achieving good input and output matching over the entire frequency range as well as maintaining high and flat gain. Good linearity and a low level of harmonic products are mandatory. As the TO-247 is not a package specifically designed for high-power RF, there are some challenges with thermal design and PCB layout as well. Information taken from the essay by the winner. Third place winner A High Efficiency Switchmode RF Amplifier using a MRF101AN LDMOS Device for a CubeSat Plasma Thruster (For more information visit: Research - SuperLab@Stanford ) The Class E amplifier utilizes the active device as a switch, operating in only cutoff (off) and saturated (on) conditions. This minimizes the overlap of voltage and current, reducing losses in the active device. To further reduce loss the Class E amplifier utilizes an inductively tuned resonant network to achieve zero voltage switching, bringing the voltage across the switch to zero before turn on, eliminating energy stored in the output capacitance of the active device that would otherwise be dissipated. This is achieved with an inductively tuned series resonant output filter.  In the Class E amplifier losses are almost entirely determined by the current conducted by the active device so a high drain impedance is desired to maximize efficiency. The drain impedance is ultimately limited by the voltage rating of the switch. For our desired output power of 40W and the maximum voltage rating of 133V for the MRF101AN this impedance is still less than 50 ohms, so a L match circuit is used to match the drain impedance to 50 ohms. The load network in our design provides a drain impedance of 15.4+12.8j. As the MRF101AN will operate in saturation a high drive level is desired. To eliminate the need for a preamplifier and allow for digital control, we use a high speed gate drive chip typically used in switch-mode power supplies, LMG1020, to drive the MRF101AN instead of a RF preamplifier. A resonant network is used to provide voltage gain at the fundamental and third harmonic, providing a quasi-square wave on the gate which helps insure the device remains in saturation. Conclusion It was a close call and highly competitive! Each participant had their own creative, unique and impressive way of displaying the capabilities of these new parts. NXP is always up for new design challenges. Ready for the next challenge?

This post entry aims at explaining the debugging process oriented to EMVCo Contactless certification of a device integrating NXP's PN5180. The structure is the following: PN5180 Antenna design considerations Before going into the debugging process for the EMVCo Contactless Analog tests we will see some important considerations for an antenna design and impedance tuning oriented for an EMVCo compliant device. Antenna tuning recommendations The first recommendation is that with the Dynamic Power Control feature the PN5180 allows us to perform symmetrical antenna tuning instead of the typical asymmetrical tuning. This symmetrical tuning provides us with a better transfer function, being able to drive more power to the antenna. The following figure shows the Smith Chart with the S11 parameter plot of a device using a symmetrical antenna tuning:   The only disadvantage of the symmetrical tuning is that we need a current limiter to avoid destroying the chip because of exceeding the chip’s limits. In the case we are documenting today, the PN5180 DPC feature is used to limit the supply voltage and therefore the transmitter current depending on the load detected by the chip. Regarding the EMC filter, the inductor should fit with the following condition to guarantee a good relation between the AGC and the ITVDD: Another consideration is about the resistor used in the reception branch. This resistor controls the receiver sensibility and as a starting point is recommended to use a value to obtain an AGC in free air of: Reader Mode only design: AGC value in free air around 600dec Full NFC design: AGC value in free air around 300dec Finally, EMV contactless transactions are performed at 106kbps which would allow us to work with a high Q factor of the overall system. This means that the power gain can be higher, but at the same time it might also lead to some issues because of the lower bandwidth. In light of this, we have to bear in mind, that if the Q factor is too high it may lead to problems in the waveform tests. PN5180 DPC calibration The Dynamic Power Control is a feature that uses the AGC value to establish different power configurations depending on the load applied to the antenna. As I mentioned before, the main goal is to protect the chip from a transmitter current level that might destroy it. The first step before calibrating the DPC is to check the correlation between the AGC value and the transmitter current or ITVDD when different loads are applied to the antenna. Basically, we will play with the distance between the load and the device to get several points with different AGC values. Based on those measurements, we can plot a graph like the following: Normally we would use a reference PICC and a metal plane or phone to check that the behavior is linear and with no big difference between those loads. Once we have checked the correlation we can proceed with the calibration process, which can be done very easily with the NFC Cockpit software. Here the important thing is to control the ITVDD and keep it always below the chip’s limit. As you can see in the figure below, without the DPC, this symmetrical tuning would lead to a voltage above the limit for positions close to the reader antenna. However, with DPC we can control that voltage at any moment. Another consideration is that we have to make sure that the DPC is calibrated to have maximum power when the reference PICC is far from the reader to avoid a lack of power in the tests at those positions. EMV L1 Analog Tests Debugging process We are going to divide this debugging process into 3 main phases which are the power tests in the first instance, followed by the waveform tests and the reception tests. The reason why we set this order is to first debug the tests that may require HW modifications which have a strong impact on the other tests. This way, for example, if you have passed all power and waveform tests, debugging the reception tests may not have an impact on the results obtained previously. Power tests Tests setup In order to debug the power tests, we will need just an oscilloscope and an EMVCo reference PICC. We will need to connect the outputs J9 and J1 of the EMVCo reference PICC to the oscilloscope and set the jumper J8 of the reference PICC in non-linear load mode. The J9 of the EMVCo reference PICC is the DC_OUT output that we will use to measure the power received by the antenna. The J1 is the LETI_COIL_OUT output and we will use it to capture the command in the oscilloscope. The overall setup is depicted in the figure below. Performing tests We have to use the trigger to capture the REQA command sent from the DTE when the reference PICC is in the position we want to test. This capture can be seen in the two figures below. The yellow channel is the LETI_COIL_OUT of the EMVCo reference PICC and the blue channel represents the DC_OUT obtained from the J1 connector. As said previously, we will use the DC_OUT to measure the voltage in the period of the signal where there is no modulation, like this part highlighted with the red squared. We have zoomed into the period to get the average value using the oscilloscope measurement features. We will use this same procedure to evaluate the power tests in all positions. Depending on the position tested, the specifications define and certain range where the voltage measured should be fitted. In this sense, the maximum voltage level is common for all planes, but the minimum voltage allowed will decrease for positions further from the terminal.  In order to identify the critical positions for the power tests, we have to identify two different scenarios, the first one with the positions that might not reach the minimum voltage established, and the positions that might exceed the maximum value. For the first scenario the critical positions are the outer positions of the plane z = 4cm and the plane z=3cm as the external positions for plane z= 3cm have a bigger radius. The other scenario is that where you can be exceeding the maximum level. This situation can happen in the central positions of the lower planes, like plane z=1 or z=0. Debugging hints In order to overcome possible issues, we will give some tips that can be used for your design. Regarding a case of lack of power, first, we have to make sure that the DPC is correctly calibrated, meaning that you are operating in gear 0 for the external positions of planes 3 and 4 and that gear 0 is operating with full power. If we have verified those two things and we still have issues, we would need to change the tuning of the antenna and reduce the target impedance. This is graphically represented in the following Smith Chart: By reducing the impedance we increase the current that the PN5180 is driving to the antenna so the voltage would increase. Is important to always verify that we are working within the recommended operating range of the chip and that we are not exceeding the transmitter current limit. In a worst-case scenario, if we cannot achieve the voltage with these HW changes we would need to evaluate changes in the hardware design, like adding a ferrite sheet or changing the antenna dimensions or position. On the other hand, if the problem comes because we are exceeding the maximum voltage allowed by the specifications we can easily solve it by reducing the power configuration of the gear used in that specific position. Waveform tests Test setup For the waveform group of tests, we will use a setup consisting of the EMVCo reference PICC along with an oscilloscope and a PC software to evaluate the signal obtained from the oscilloscope. In our case, we will use the Wave Checker software from CETECOM. We need to connect the output J9 of the EMVCo reference PICC to the oscilloscope and set the jumper J8 of the EMVCo reference PICC in the fixed load position. The oscilloscope needs to be connected to the PC or laptop, so the software is able to get the waveform and analyze the parameters needed. Type A tests The waveform group of tests for Type A consists of the following test cases: TA121: t1 TA122: Monotonic Decrease TA123: Ringing TA124: t2 TA125: t3 and t4 TA127: Monotonic Increase TA128: Overshoot Some of these test cases are directly related to the parameters defined for the specific modulation phase for Type A at 106 kbps. This modulation phase along with the respective parameters is depicted in the figure below. When the Wave Checker gets the oscilloscope capture, it automatically analyzes the signal, performing all the measurements and comparing them with the specifications limits. Debugging hints for Type A The PN5180 has a few registers and parameters to control the wave shape generated by the NFC chip and transmitted by the antenna. These are the most relevant ones: TX_CLK_MODE_RM (RF_CONTROL_TX_CLK register) Rise and Fall times (RF_CONTROL_TX register) TX_OVERSHOOT_CONFIG register From all the different test cases we will show how to debug the t3 and t4 test case as it is usually the most problematic. For this purpose, we will start from a certain configuration where the waveform tests show the following results, with a fail in the t3 and t4 test case. In order to tackle this problem, we will rely on the TAU_MOD_RISING parameter from the RF_CONTROL_TX register of the PN5180. In this case, as the timings are slightly above the maximum allowed in the specifications we will decrease the TAU_MOD_RISING 3 points and execute again the tests. The results after the modification show that all test are passing with a certain margin:   Another parameter that the PN5180 has and can be used for the waveform tests is the TX_CLK_MODE_RM parameter from the RF_CONTROL_TX_CLK register. Below you can see two graphs that clearly illustrate the effect of this parameter over the waveform.  As you can see from the two figures, by changing the default high impedance configuration of 001, to a low side pull configuration the waveform results in a smoother decay of the envelope. Type B tests For Type B waveform, the specifications define the following test cases:  TB121: Modulation Index TB122: Fall time TB123: Rise time TB124: Monotonic Increase TB125: Monotonic Decrease TB126: Overshoots TB127: Undershoots Again, these tests are based on the different parameters that can be identified for the modulation phase of the Type B commands: Debugging hints for Type B The register and parameters that the PN5180 includes to control the waveform for type B are: TX_RESIDUAL_CARRIER (RF_CONTROL_TX register) TX_CLK_MODE_RM (RF_CONTROL_TX_CLK register) TX_UNDERSHOOT_CONFIG register TX_OVERSHOOT_CONFIG register For Type B, we will study the modulation index test case, as it is the one that needs to be adjusted more often. In this case, we start from a situation where the device presents problems in the modulation index at 1 cm, with a value below the limit. In order to make corrections of the modulation index we will use the TX_RESIDUAL_CARRIER parameter from the RF_CONTROL_TX register. This parameter controls the amplitude of the residual carrier during the modulated phase. For the present problem, we will increase it by 4 points and rerun the test. As you can see in the picture below, the modulation index is within the specifications limits with margin.  Adaptative Waveform Control The PN5180 has another interesting feature called Adaptative Waveform Control that is used to set a different transmitter configuration depending on the gear and protocol used at any moment. This way we can easily debug by positions and use specific configurations for a certain group of positions without the need of rerunning all the tests for the rest of the positions. With the AWC feature we can control the: TAU_MOD_FALLING TAU_MOD_RISING TX_RESIDUAL CARRIER We can see in the table an example of an AWC configuration for Type B. Where we have changed the Residual Carrier from gear 2 onwards. As you can see, It is also configured with a change in the falling and rising times from Gear 1. As you can see this Adaptative Waveform Control feature along with the DPC represent a powerful tool to easily debug waveform tests without a change in the HW. Reception tests The reception tests purpose is to evaluate the ability of the device to identify and correctly demodulate the responses from the PICC when this response comes in the limits of the specifications for amplitude and polarity of the modulation.  Tests setup The tools and setup needed to debug the reception tests for EMVCo are depicted in the following figure: Oscilloscope to capture the signal received by the reference PICC. Arbitrary Waveform Generator to generate the response of the PICC. PC Software to control the AWG and load the EMVCo responses to the EMVCo reference PICC. For our case, we will use the Wave Player software from CETECOM. EMVCo reference PICC. This time, we will use the output J9 of the reference PICC to the oscilloscope to capture the command from the reader and trigger the injection of the response from the waveform generator to reference PICC, connected to J2. We should connect the waveform generator to the computer that has the Wave Player software installed to load the EMVCo responses. Performing tests As said previously, the reception tests aim at testing the ability of the device to correctly interpret the response when it is generated at the limit of the amplitude and polarity of the modulation. Considering the positive and negative polarity and the maximum and minimum amplitude of the modulation we have the following four test cases that are performed both for Type A and Type B: Tx131: Minimum positive modulation Tx133 - Maximum positive modulation Tx135 - Minimum negative modulation Tx137 - Maximum negative modulation To debug these tests with the PN5180 we will use: RX_GAIN (RF_CONTROL_RX register) RX_HPCF (RF_CONTROL_RX register) MIN_LEVEL (SIGPRO_RM_CONFIG register) MIN_LEVELP (SIGPRO_RM_CONFIG register) The procedure is basically to use the Waveplayer to set the amplitude and polarity of the response and check in the device is the response was correctly received and demodulated. Debugging hints To debug the reception we will test different configuration for the RX_GAIN and RX_HPCF parameters that control the reception filters, amplifier and ADC blocks from the receiver branch. These receiver blocks are pictured in the diagram below. Depending on the values used for the RX_GAIN and RX_HPCF parameters, the filter will be defined accordingly. The following table shows the filter characteristics in relation to those values: If we don’t find a correct value to pass the test at a certain position, we should modify the Rx resistor in order to increase or decrease the receiver sensibility. Adaptative Receiver Control In the same line as the Adaptative Waveform Control, the PN5180 includes the Adaptative Receiver Control that can be used to define different reception configurations depending on the gear and protocol used. With the ARC we can control all the registers involved in the reception and apply a correction to the preconfigured value depending on the gear used.  We can see an example of the Adaptative Receiver Control configuration in the following table, where we have defined a correction of -1 to the MIN_LEVEL and the HPCF parameters from gear 1. We can also see that the RX_GAIN parameter has a correction of +2 from gear 0. The ARC is very useful when we can't find a proper configuration for all positions and we need a different set of values depending on the positions tested. Rx Matrix tool Another interesting tool for debugging the reception tests is the Rx Matrix tool. This tool is used to launch and tests different receiver configuration in an automated way. The Rx Matrix tool is integrated into NXP's NFC Cockpit and you can control the Arbitrary Waveform Generator to set the amplitude of the modulation used for the tests. We can select which parameters we want to change and in which range we want them to be tested and the Rx Matrix will automatically run all the possible combinations in a sweep.   With the Rx Matrix tool, we can select the expected response and the number of iterations we want to try for every possible configuration. That way we can obtain a success ratio for the communication and easily identify the best configuration for the position tested. An example of the Rx Matrix is given in the figure below. We have fixed the RX_GAIN and RX_HPCF parameters and performed a sweep for the MinLevel, testing it from a value of 0 to 8. We have set the Rx Matrix to execute 50 iterations for every configuration, obtaining the success ratio results plotted below. As you can see the Rx Matrix along with a Waveform Generator is a powerful tool to find the optimum receiver configuration in a short time and in an effortless way. PN5180 Ecosystem The PN5180 comes with a complete and useful product support package including: The demokit, that can be used to get introduced to the product and check its features. The NFC Cockpit, that we have talked about during this article, and that represents a powerful tool to control the PN5180 with a very intuitive and useful interface. We srongly recommend that you integrate this tool in your final device as it may save you a lot of time during the debugging phase. A complete documentation including the updated product datasheet, or a set of application notes to guide you through all the designing process, from the antenna design guide to the DPC configuration or use of the Rx Matrix tool. Last but not least, the NFC Reader library which is the recommended software stack for NXP's NFC frontends and NFC controllers with customizable firmware. NFC Reader Library The NFC Reader Library comes with built-in MCU support, but it can also run on different MCU platforms, as well as non-NXP. The library has been built in such a way that you can adapt it and implement the required driver for your host platform. Other characteristics are: It is free of charge and you can download the latest release from NXP’s website. It is a complete API for developing NFC and MIFARE-based applications. Includes an HTML-based API documentation for all the components, which is generated from source-code annotations.  Finally, the release includes several examples and applications. Among the examples and applications included in the NFC Reader Library we can highlight two applications that are very useful for the preparation of the Device Test Environment required for the EMVCo certification:  The SimplifiedAPI_EMVCo for the digital testing The SimplifiedAPI_EMVCo_Analog for the Analog testing. You can control all the parameters involved in both applications using the phNxpNfcRdLib_Config.h configuration file. The identification and modification of these parameters should be very easy as the code is well documented, like you can see in the code chunk in the image: Further information You can find more information about NFC in: Our NFC everywhere portal: https://www.nxp.com/nfc You can ask your question in our technical community: https://community.nxp.com/community/identification-security/nfc You can look for design partners: https://nxp.surl.ms/NFC_AEC And you can check our recorded training: http://www.nxp.com/support/online-academy/nfc-webinars:NFC-WEBINARS Video recorded session

This post entry provides a detailed description of the OM29263ADK kit, a new antenna tuning development kit specially designed to facilitate the NFC antenna prototyping process. This document has been structured as follows: OM29263ADK kit contents This kit consists of a single PCB board that includes:  A pre-matched antenna of 2 turns and a size of 77 by 113 mm.  A second pre-matched antenna of 4 turns and a smaller size of 20 by 20 mm.  And, 8 extra boards to prepare the matching for custom antennas. As a result, this kit is a perfect resource for different purposes such as evaluating the RF performance of different antenna sizes and, for prototyping your custom antenna quickly. In addition, this NFC antenna development kit is compatible with our existing product support package. You can directly connect it to CLRC663 demoboards, as well as to PN5180 and PN7462 demoboards after a minor tuning. Using OM29263ADK kit with CLEV6630A or CLEV6630B The process is really straightforward… First, take one CLRC663 demoboard and separate the main PCB from the antenna & matching circuit. The board includes cut lines, so you can divide both sections easily by only using your hands. Second, break the kit OM29263ADK PCB so that you separate the pre-matched antenna from the other PCB parts. Then, it is just a matter of connecting the two parts together. The kit antenna includes pin male connectors while the CLRC663 board includes the corresponding female connectors. Therefore, hook up the antenna with the main board, solder the connectors and that’s all. We can observe that when we connect the kit large antenna to the reader PCB, the  impedance measured with our network analyzer shows that the tuning is adjusted to approximately, 19 Ohms. This is the result obtained without any hardware modification The same process applies for the smaller antenna: Similarly, we can observe that when we connect the kit small antenna to the reader PCB, the  impedance measured with our network analyzer shows that the tuning is adjusted to approximately, 36 Ohms. This is the result obtained without any hardware modification: Using OM29263ADK kit with PNEV5180B or PNEV7462C In case you are interested to connect the OM29263ADK kit antennas to the PNEV5180B or PNEV7462C boards, the preparation process is the following: First, separate the antenna and the matching section from the PN5180 or PN7462 demoboards, as before, using the cut lines. Then, take one kit sample, and separate the pre-matched antennas for the other PCB parts. And finally, adjust the EMC filter. The EMC filter adaptation is required because the kit antenna is prepared for asymmetric tuning while the PN5180 and PN7462 original antenna use a symmetrical tuning. The main difference between both types of tuning is the cut off frequency. The symmetric tuning uses a cutoff frequency around 15MHz, while the asymmetric can go up to 22 MHz. In practice, for this adaptation, we only need to change the value of the capacitor C0 in the main board. For instance, the existing 220 pF capacitor can be replaced for another one of 68 pF. Using OM29263ADK kit to connect your own antenna coil This section describes how to use the kit PCB boards for our custom antenna tuning. For this task, the list of material that we need is: A reader PCB board, in the example, we picked CLRC663 One of the PCBs for antenna matching included in the kit And, the any antenna to be matched  In our case, we have selected one sample antenna available in our lab. The following explanation will be guided using this antenna as a reference, but any antenna can be tune using the same process. The usual list of steps to tune a custom antenna are: First, we need to define target impedance and Q factor, as design parameters for our reader Then, we will characterize the antenna coil and find its parameters After that, we will design the EMC filter With this, we will calculate the matching components using an Excel sheet Afterwards, we will assemble the calculated components and measure the first results. We will take field measurements, which probably will show that it is not perfect, so we may need to adapt the matching values With these fine-tuned vales, we will re-assemble again And finally, we will design the receiver circuit. Define target impedance and Q-factor First, we start defining the target impedance and Q-factor. The target impedance is a design parameter, which needs to be chosen according to our needs whether we want to go for maximum field strength or minimum battery consumption or a trade-off in between. Typically, reasonable values are between 20 Ohms and 80. Another important design parameter is the Q factor. The Q factor is a dimensionless parameter indicating the performance of a resonant circuit. The higher the Q factor, the higher the read range. On the other hand, increasing the Q factor also reduces the bandwidth of the circuit. As a result, in practical implementation, Q-factor values below 30 are demonstrated to fit well for the ISO14443 wave form timing requirements and corresponding spectrum.  For our tuning exercise, the design parameters chosen are an impedance of 20 ohms and a Q factor of 25 Measure antenna coil Next step is to characterize the antenna coil. Any antenna coil has an input impedance. This input impedance is complex and consists of an inductance, capacitance as well as some losses represented by a resistance (R). The actual values depend, among others, on antenna material, thickness of conductor, distance between the windings, number of turns, etc.  The coil characterization needs to be done with a network analyzer. It could be a high end, such as Agilent or Rohde & Schwarz, which is powerful, accurate, easy to use, but expensive. Or we can also go for low end solutions, such as the miniVNA PRO, which is cheap compared with the previous ones, and accurate enough for our needs. In our case, the characterization of our lab antenna shows:  An inductance around 1.3 uH And a resistance of 2.5 Ohms Design EMC filter The next step is to design the EMC filter. As we are using CLRC663, we will go for an asymmetric antenna tuning. Good inductor values are between 330nH and 560nH. and 21MHz cutoff frequency is ideal for asymmetric tuning. Fixing this two parameters, we can easily calculate the required capacitor component for our EMC filter with the formula below. In our example, we need to use a capacitor of C= 122 pF. With this, we just pick up the closer commercial value from our components box Calculate matching circuit components We have characterized the antenna coil and completed the EMC filter. Now, we can calculate the matching network components. The matching components need to be calculated so that the maximum power from the reader is transmitted to the antenna. This happens when the equivalent impedance seen from the reader IC only has the real part, without the complex part. There are some complex calculation involved in the process. In order to avoid these cumbersome formulas, NXP provides a useful Antenna Tuning excel sheet that calculate the appropriate components for you. Below, you can see a screenshot of the Excel sheet in the slide. This sheet calculates C1 and C2 matching values according to the inputs expected from the user. These are The measured antenna coil parameters The EMC filter parameters. The target impedance and Q-factor of our design With these values, The Excel sheet calculates and outputs the value of the matching components: C0, C1, C2 and Rs. In our exercise, the output values calculated for the matching network by the Excel sheet are C1 around 43 pF and C2 around 144 pF Assemble and measure Typically, the calculated values do not match with commercial components. The easiest way is to add components in parallel to get as close as possible to the calculated values. If we take a closer look to the kit antenna matching PCB board, the pad location is the following: We have two slots for C0 – so we can have two capacitors in parallel to achieve a better accuracy on the capacitance value we need to achieve We also have two slots for C1, for the same purpose We have two more slots for C2 soldering We also have two slots for the dampening resistor, in case we need to reduce the Q-factor of our antenna. And finally, one slot for the receiver resistor circuit. After the first component assembly, it is worth performing a field measurement to find out how accurate our matching is in reality. Typically, the measured impedance is different than the impedance calculated in the simulation. Therefore, the calculated matching components were not 100% accurate. But we knew that in advance. We were aware that we were just getting a rough approximation to the antenna parameters. As a result, a good matching is achieved after a number of iterations according to the field measurements that we obtain. As a general rule,  C1 changes the magnitude of the matching impedance and C2 changes its imaginary part. In our exercise, after soldering the first components, the equivalent impedance is around 19 Ohms but it also has a significant imaginary part. As a result, it can be fine-tuned towards better performance. We modified C1 and C2 a couple of times until we found out the final values that work better. obtaining a impedance with only real part at 22 Ohms (C1= 36pF and C2=154 pF). Adjust receiver circuit The last step of tuning our antenna is to design the receiver circuit. The Rx circuit that consists of a voltage divider and a coupling capacitor connected from the output of the EMC filter to the RX pins of the NFC reader. The objective is to set the voltage level at the reception pins to achieve the compromise between a good sensitivity. For CLRC663 plus, the serial resistor is in the range of 7 and 15 kΩ. You can start with a 11 KOhm value, then, the resistor can be adjusted depending on the voltage measured in the Rx pins. If the voltage at Rx pin is higher than 1.7 V, it is recommended to increase the resistor value and if the voltage at Rx pin is below than 1.2 V, it is recommended to decrease the resistor value. Using OM29263ADK kit to evaluate the performance of different antenna shapes The section covers how you can use the antennas included in the kit for performance comparison. Please note that this lab exercise is shown only for illustrative purposes on how the kit can be used to evaluate the performance of different antenna shapes. As an example, we defined a sample scenario where we want to characterize how the field strength decreases with distance when using antennas of different size. For that, we used the following setup: A class 1 ISO14443 Reference PICC A scope A CLRC663 board connected to the small antenna A CLRC663 board connected to the large antenna A ruler to measure the distance The measurements were taken in this way: We tuned the large and small antennas to 20 Ohms We connected the board to the laptop, and we executed the NFC Cockpit tool to control the RF field. We measured with the scope the voltage level obtained by the ISO14443 Class 1 Reference PICC while we increased the distance. Background information Before actually showing you the results, it is worth it to review a couple of antenna design principles to properly understand the results. Coupling coefficient Before actually showing you the results, it is worth it to review a couple of antenna design principles to properly understand the results. The coupling coefficient is a parameter that indicates how much of the magnetic field generated by the reader is picked up by the card. The coupling coefficient takes a value between 0 and 1 If the coupling equals 1, it means we have a perfect coupling, all magnetic field lines are picked by the card If the coupling equals 0, it means we have no coupling at all, no magnetic field lines are picked by the card The key message is that the coupling coefficient is just a geometric quantity. It depends on: The reader and card antenna dimensions (both antenna radius) Their relative position (whether in parallel or perpendicular, they will pick a different amount of magnetic field lines) The distance between them And the magnetic properties of the medium Mutual inductance Very related to the coupling coefficient, we have the mutual inductance. The mutual inductance allows us to determine the voltage induced in the card antenna, that depends on: Coupling coefficient  Better coupling, higher the voltage Driver current  The higher the current we drive in the reader antenna, the stronger the magnetic field Antenna inductance Precisely, in this setup, we are going to measure the voltage perceived by the reference PICC when using two different antennas. Antenna tuning components used for the large antenna First, we prepared a tuning of 20 Ohms in the large antenna. This task was done using the process described above. As an example, we selected a low Q-factor of 10, which helped us to accommodate high bit rates for ISO14443. In the figure below, you can see the components we assembled to tune the large antenna near to 20 Ohms. Antenna tuning components used for the small antenna Second, we prepared a tuning of 20 Ohms in the small antenna so that the results are comparable. The same Q-factor and EMC filter values were used, but obviously, as the antenna size is different, we used different C1, C2 and Rs values to achieve the same equivalent impedance OM29263ADK large antenna vs small antenna The following graph shows the results we obtained: The blue line, represents the DC output voltage obtained from the Class 1 Reference PICC as we increase the distance from the reader using the large antenna… The green line, represents the DC output voltage obtained from the Class 1 Reference PICC but using the reader with the small antenna connected. As a result, what we see is that at close distance, both antennas are able to deliver the same field strength. However, as distance increases, the RF field of the small antenna starts to attenuate quickly from 2 cm distance of the reader while the RF field of the large antenna is more or less stable until 5 cm, after that, it starts to attenuate quickly as well. Potentially, what we can conclude is that for this setup, we might be able to get more reading distance with the large antenna. ISO/IEC14443 vs ISO/IEC15693 reader - Quality factor We need to bear in mind that our antenna is not only for energy transfer, but also it should match with the waveform requirements. Therefore, from the practical point of view, the Q factor of the system is limited by the bandwidth as if we increase the Q, we increase the field strength but we decrease the bandwidth. Our reader can be optimized whether we are designing a reader for ISO14443 or ISO15693 as the signals modulation and timing requirements of the rise and fall times for both RF protocols are different. Actually, in practice, ISO15693 allows us a higher Q factor because there is a lower bandwidth requirement as the waveform timings are more relaxed and, the power transfer requirement is lower than ISO14443. For such optimization, you can refer again to NXP antenna tuning excel sheet. If you recall, one of the input fields of the excel sheet is the Q-factor. Therefore, you can introduce here a value below 30 for ISO14443 readers or below 100 for ISO15693 readers. The excel will output reasonable matching values for the first components adjustment. After that, you can do a fine tuning according to the process I explained before.

Demo Ricardo Anguiano describes a memory game demo built by Mentor Graphics for their Embedded Systems Division's 20th Anniversary. The game uses 36 FRDM-K64F boards with Adafruit 2.8" capacitive touchscreens in a 6 x 6 grid. The FRDM-K64F boards run the Nucleus RTOS from Mentor Graphics. The FRDM-K64F boards are connected over Ethernet to a touchscreen-driven Boundary Devices BD-SL-i.MX6 (formerly the SABRE Lite board) game controller which also runs the Nucleus RTOS. Players start the game by viewing and studying the position of all 36 digital cards, the cards are flipped and the player must touch matching pairs for points before time expires. The memory game generated lots of interest with players coming back multiple times. It was a great way to introduce the ARM TechCon crowd to the Nucleus RTOS, which enjoys wide success in a number of vertical markets and product categories like industrial, medical, IoT, wearables and automotive. The safety-certified version, Nucleus SafetyCert has been verified and documented to meet the certification requirements for device manufacturers developing safety related software for avionics requiring DO-178C Level A, industrial requiring IEC 61508 SIL 3, medical requiring IEC 62304 Class C, and automotive requiring ISO 26262 ASIL B. Features • A fun memory game built on Mentor Graphics' Nucleus RTOS, deployed on over 3 billion devices worldwide. • NXP FRDM-K64F and i.MX6 based hardware NXP products ARM Cortex-M4|Kinetis K64 120 MHz 32-bit MCUs i.MX6Q|i.MX 6Quad Processors|Quad Core Tools FRDM-K64F|Freedom Development Platform|Kinetis MCUs https://boundarydevices.com/product/sabre-lite-imx6-sbc/  Mentor Graphics Links https://www.mentor.com/embedded-software/nucleus/ https://www.mentor.com/embedded-software/nucleus/safety https://blogs.mentor.com/embedded/blog/2016/10/31/testing-your-memory-at-arm-techcon/
