W6PQL has designed and built a 1KW SSPA for 1.8-54MHz using an LDMOS
device. Freescale I think.
he has also designed a pretty stout Low Pass filter designed for 1.5KW
1.8-54 MHz.
He can get 1.2KW out of it at saturation with 2-3 W drive.
A pair of these devices @ 750W could do 1500W all day any mode. but then
the power supply becomes the limiting factor.. 50V at 70amps?
