Hi all, I need to improve the range coperture of my custom board based on MC13213. I'm thinking to use an external LNA, like MBC13720, to increase the output power. Someone have implement a custom board with this kind of device? I have already asked to Freescale support but they haven't an application note with this device or a reference manual.
Would anyone please share what is the minimum SNR required for detection and the Noise figure for Freescale MC13213 SRB board. This is needed to calculate (theoretically) by what factor the range can be extended by using an LNA with SRB.
If anybody has single antenna schematic for MC13213 (ZigBee modem) with MBC13720(LNA) in tranmit path, please share it with me. Also, I would like to know with this LNA what could be the max range I can achieve.
Hi ZigBeeficator, thank you for your design. It's possible to use an external LNA like MBC13720 with a Single Port configuration and use the CT_Bias pin for set the LNA in bypass mode or gain mode? In this case I don't use the Dual Port Configuration like you have suggested.
