RF power amplifier 80W by C2782
Thursday, August 6th, 2009
This is a pretty conventional design, using bipolar transistors in a tuned class C circuit. 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.
Bipolar VHF power transistors have a severe affinity for [...]
