This Power amplifier is equiped with two Philips bipolar transistors : the BLV10 & BLW87.

As lots of FM amplifier design ,the RF transistors are in a class C 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 21 dB gain with a 55 to 65% efficiency.

(No tune is needed to cover all the FM Band).
