I can hardly imagine just about any device like this having an Ft so

I plan on building a 500 KC transmitter, 200 watts output. I have
never worked with power FETS before.

What is the selection method used in determining which FET to use??
I see some great FETS
cheap.

Example: IRFP254

250 volt Vdss

RDS on .14

Amps 32 amps

Rise time : 51 NS

Cost; 2.50 each

The data sheet does not spec any freq's ( Ft) like bipolar
transistors?? How do I select the right FET??? freq range

Thanks!!!

The 500 KC transmitter will run at 28 VDC


Well a friend of mine once wanted to build a mobile transmitter for
455khz AM and 10.7mhz FM so he could tell the bozo in the car ahead of
him where to go after he cut him off.....
