This Fm rf power amplifier has 2 transistors from Philips : BLV 10 and BLW 87. The 2 rf transistors work in class C and this fm amplifier has a total gain of 21dB ( 100 X ) and efficiency 55 – 65%.
One low pass filter with 9 components ensures 60dB rejection on the second harmonic.
There is no need for tune-up to cover the whole 88 – 108 MHz FM frequencies.
