Polyfet has a 2014 technical bulletin on their website, TB239. It uses
their LY942 LDMOS transistor to make a flat 2-30 MHz 400 watt linear
amplifier with 20 dB gain, using 50 volt parts. Its a compact layout and
there is a full parts list along with plots. Has anyone built one of
these? Its not 1200 or 1800 watts, but has decent 3rd order IMD results
listed.
