hello all...

i need help, i need your suggertion, please suggest the available transistor for HF PA design at 3 MHz - 30 MHz
characteristic: low power or high power...high gain

application:radio manpack
 

For a low power application, I believe it would be a microwave transistor.

If it's RF at high power, then is it for a transmitter? It will probably require a TO-3 package and a configuration to deliver a quick slew rate. Or, tubes are still found to be useful in a transmitter output stage.

Transmitter power must comply with regulations because it requires a license if you go over a certain watt rating.

you were given a good choice in your other identical thread

try and avoid doing multiple threads on the same subject.... makes it hard for people to follow

Check NXP website for transistor.
they will have good transistors.
