This new FM Power amplifier is equiped with the bipolar transistor: the BLV10.

We've chosen the synthesizer n°2 (described on this site) to drive this amplifier unit consequently we need the 2N3866 driver stage to boost properly the BLV10 transitor.

All the impedance networks (Input & Output) have been determined by using the softwares: Mimp.EXE & Genesys.

Due to the good harmonic rejection of the design, a low pass filter is not necessary.

Frequencies	Output Power Level	Gain	Current	Efficiency
88 MHz	8.5W	22.3dB	1.25 A	50 %
98 MHz	8 W	22dB	1.1 A	55 %
108 MHz	7.5 W	21.7dB	0.9 A	61%

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

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