LDMOS Amplifier for 630 meters

Working on my LDMOS amplifier. Getting a lot closer. Its putting out 200 watts now. Just a little more tweaking and it'll be done.

Here's the schematic. It took 10 revisions to get everything working to my satisfaction.

I have reached my goal. I got 250+ watts out. Next, I just have to put together a submission to the NXP homebrew RF amplifier competition.

Here's my new video which includes a more information. https://www.youtube.com/watch?v=En6QonSDCnU
