Fet driver circuit board

630 meter 100W class D push-pull pwr amp designed to operate with 0 to 4 dbm input (about 632 mv P-P to 1.0 volt P-P ) into a 50 ohm load. Everything is in the enclosure except the low pass filter. The output stage is a scaled down verison of W1VD 500W Amp with the same rugger output FET transistors with a redesigned driver circuit. The Amp will run 35 to 100 watts into a resonant antenna with 14-24 volt power supply

I use this Amp with a K3 but also works with Flex, Kenwood TS590,Kenwood TS990, SoftRock RXTX, Some Icom's and other transciver and QRP labs U3 as a WSPR beacon.
