I'm still way off finishing my 100W TX and have a pile of tested PCB's that will O/P 400W @ 48V (@10A).
They have an AD9850 DDS with a PIC storing 16 Channels.
Drivers are the latest (need 12V @ 150mA)
Will need bolting to a modest heatsink or metal case with fan.
Efficiency is decent at 90% as it push pull class E with four GaN FETs.
Everything is on the PCB so you'll just need a PSU and modulator.
Will O/P 600W @ 60V but will need some serious cooling, at the 400W level the cooling can be passive....
$300 ONLY....
