Project Video: MRFX1K80H 50 MHz

Project Brief
This amplifier is intended to be driven with a modern transceiver with 100 watts output on 50 MHz. To protect the MRFX1K80H from overdrive a series of RF pads are used to reduce the input to the proper level. The input matching is accomplished by using a 9:1 conventional RF transformer formed on an Amidon BN 61-202 core. An 82 nH inductance is in series with the high impedance winding of the transformer. This arrangement yielded an input match of 1.3:1 SWR over the entire 6-meter Amateur band when measured without the pads. Shunt gate resistance is used to prevent oscillation at low frequencies. This is the same approach used in the 27 MHz test circuit from NXP. Bias will be supplied by a DAC driven by the microcontroller that will manage the finished amplifier
