http://www.cqham.ru/projects/7mhz_trx/e_mc3362.htm Webb20 W HF Power Amplifier - A HF power amplifier with a push-pull of AFT09MS015N. The (small-signal) gain of the amplifier is around 26 dB in the lower HF band and goes down to about 24 dB on the higher end and still around 21 dB at 50 MHz. Its input matching is relatively good at the lower HF and degrades above 10 MHz. WebbThe Transmit Driver stage is straight out of EMRFD but uses a 2N2222 (TO-18 Style) and a BD139. All other circuit elements are as in the 2N3904/2N3866 EMRFD Design. This stage can be run at about 400 Milli-Watts. The audio amp is a 2N3904 driving an LM386 and the microphone amp is a single 2N3904. how does a loudspeaker use electromagnets
