LDMOS Amplifier for 630 meters

They arrived! A pair of 300 watt LDMOS mosfet amplifier chips. These are for the next 300 watt VLF amplifier build.

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

Still cranking away at the LDMOS amplifier I am getting 150 watts out still. I'm now optimizing each section.

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.
