2200 meter class D Power Amp designed to produce 200 watts into a 50 ohm load with only 0 dbm (1mw ) input .The output stage is a push-pull design using a pair of RFP250’s , each of these fet transistor will handle 250 watts, this is a very rugged output stage. The driver circuit for the output stage uses a fet driver chip with associated parts to control the drive and the bias of the output power transistors. The Amp will produce 48 to 200 watts into a resonant antenna with a 14 to 28 volts power supply.
