Hi,I want to amplify DRA818V(0.5/1 W VHF transceiver module) output with C1971 175Mhz VHF PA transistor.here is DRA818V schematic:
This schematic also includes LPF,But filter output is connected to antenna.
As already said I want to connect output to 1971 power amplifier before connect to antenna.
Should I use this LPF before 1971 amplifier circuit? Or shift it to output of 1971?Please help.
Thanks.
