LDMOS Amplifier for 630 meters

Working on my new 300 watt LDMOS amplifier project for 630 meters. Trying different designs for the input matching circuit

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
