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.

RF Amplifier Broadband 88-108 MHz 8W

This RF amplifier for FM 88-108 MHz with no tune (broadband) needed to cover all the FM Band. You need the 2N3866 driver stage to boost properly the BLV10 transitor.

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

RF FM Power Amplifier Schematic-PCB

Due to the good harmonic rejection of the RF amplifier design, a low pass filter is not necessary. Or you can download RF Filter Design AADE and RF Filter Design Software-SVCFilter.

This RF amplifier has a 22 dB gain (with driver stage) and provides 8W with a 55% efficiency.
