Frequency response rolls off too much for those transistors. They were made
to work below 2 mhz. HOWEVER, there are the high voltage mosfets from
Advanced Power Technology that work in the 300-1,200 VDC range deserve
discussion. The devices are targeted for RF designs < 75 Mhz, and are very
cheap by most measures (not Rich). Lots of class "E" circuits for them...
APT has many app notes on them... check them out!
