A 4 FET Push/Pull input circuit schematic.

The link will take you to the Rochester (NY) DX Association website Photo Gallery, Class E Amplifier Schematics section, where you will find a jpeg image of the circuit.

Thanks to RDXA for allowing me to post images on their web site.

This input circuit is a 50 ohm input for driving (4) IRFP32N50K FETs on 40 meters. These parts ($6ea) are capable of developing 600-1000 watts PEP in a Class E saturated mode at about 90% efficiency. The output circuit (no shown) is the usual 1:1 transformer followed with a series tuned network matching up to 50 ohms. Driving power is 2-3 watts/FET.
