    Browse through a total of 3 rf amplifiers.

    BLY94 50W RF Amplifier Circuit This fm rf power amplifier circuit is built with BLY94 transistor which delivers up to 50W at 175MHz and has a power gain of 7dB, arround 5x power amplification. But in this schematic bly94 is working in 3 meter band, FM 88-108 MHz, so it has a higher power gain, 8dB – 6x. So if we use a good quality trimmers and coils...
    300W FM RF Amplifier Circuit This 300W RF power amplifier for your fm transmitter has 2 x TP9383 transistors. 300W radio power amplifier for 88 – 108 MHz band. 300W RF power amplifier circuit...
    20W FM RF Amplifier Circuit This FM RF power amplifier has 2 transistors from Philips: BLV10 and BLW87. The 2 rf transistors work in class C and this fm amplifier has a total gain of 21dB (100x) and 55 – 65% efficiency. One low pass filter with 9 components ensures 60dB rejection of the the second harmonic. There is no need for tune-up to cover the...
