Selecting power Fets for 500 KC transmitter
Greetings!!!
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
