ARRL Homebrew Challenge 3 radio update: Power Amplifier complete

The power amplifier is complete. with -10 dBm in from the front-end mixer my driver will provide 10 watts out. My final power amplifier will provide 110 watts out with the 10 watts of drive power using a push-pull LDMOS transistor.

This is very exciting. Hopefully 100 watts will be sufficient to make some 10m and 6m contacts later this fall when the radio is complete :)
