Very High Performance Transverter for 432 MHz is For SALE
It has two (synchronous) receive converters that are composed of external
LNA (ATF-54143) and high IIP3 stage in base xvrt with SGA-6389, BPF, 20dBm
mixer and IF AMP.
The local oscillator (137 MHz) uses the same design as the one in Javornik.
The only difference is that 3 times higher LO frequency is needed, so the LO
chain is a little bit more complex.
The TX converter is basically the same as in 2m xvrt. The Mitsubishi FET
power module RA45H4047M is used as the final amplifier delivering 45W of
clean output signal.
