This Power amplifier is equiped with a bipolar transistor,the famous MRF317
As lots of FM amplifier application ,the power transistor is in a C class bias.
All the impedance networks (Input & Output) have been determined by using the software: Mimp.EXE.
A 9 elements low pass filter ensures that we meet at least a 60 dB rejection from the carrier.(RF Simulation with RFSIM99)
The FM amplifier has a 10 dB gain with a 60 to 65% efficiency.
The Input VSWR is around 1.4 and there’s no problem to reach the max power in all the FM band..
