Thanks to the use of two stages, the amplifier can be driven to full power with less than 1 watt driving power, so that a large gain margin results in this transmitter. วงจร RF Amplifier 80W ด้วยทรานซิสเตอร์ C2782 อ่านต่อ [...] [...] This is a pretty conventional design, using bipolar transistors in a tuned class C circuit.
