[Amps] APT parts

[John T. M. Lyles]

Give Dick Frey (K4XU) a call up there. He is apps 
engineer and can inform you about those parts and 
others for linear use. Also, George Krausse, 
formerly of Directed Energy-Ixys, is their VP, RF 
Products now.

>It looks like Advanced Power Technology has some 300 volt VDMOS
>FETs that do 750 watts in modes A-E (ARF1505).  A push-pull
>pair of them would be very close to legal limit (US) from one
>module.  Two of those modules could be run at 75% ratings with
>splitter/combiner or in push-pull to generate a conservatively
>rated legal limit device.  Of course with 17 dB gain, an ARF1505
>amplifier would require a drive stage (or the 400 watt FT-9000
