RF Amplifier Broadband 88-108 MHz 20W


This RF amplifier for FM 88-108 MHz with no tune (broadband) needed to cover all the FM Band. This RF Power amplifier is equiped with two Philips bipolar transistors : the BLV10 & BLW87.

All the impedance networks (Input-Output) of this RF amplifier have been determined by using the softwares: Mimp.EXE.

This RF Amplifier need a 9 elements low pass filter ensures that its harmonic frequency meet at least a 60 dB rejection from the carrier.(RF Simulation with RFSIM99)
This RF FM amplifier has a 21 dB gain with a 55 to 65% efficiency.
