Start with the 1500 watt peak output amplifier described in the old APT application note, APT9701, which posits 25¢/watt for a Class C amplifier section with 70% efficiency at 27 MHz (ISM band,
I think you'd need a feedback system - polar or cartesian loop, for example. The AM/PM in the output stage will be severe, and probably beyond simple pre-correction in open loop. You can buy the who
Combined replies to comments: you are going to use dissipate 150 watts in the heatsink vs 600? Hi Todd, Wellllll, to my limited understanding, Class E provides poor utilization of (expensive!) FET Dr
