Here is 600W linear amplifier of the HF that I make recently. It is completed, but is considerably almost compact. In the circuit, it is designed EB104 of Motorola in basics. I use four STMicro SD2931-10 in substitution for MRF150.I can use it from 2Mhz to 30Mhz, but, as for more than 21MHz, adjustment of impedance of an output transformer becomes bad, and electricity efficiency declines.In coordination with a capacitor of an output transformer, I want to wrestle with optimization.
