Re: U3S RF Power Transistor

 

I made an RD06HHF external amp, for my QRP Labs rigs and for general use.



I have one of my QRP Labs rigs set for about 200mw output, and pass it via a 3db attenuator.

I prefer to use an attenuator because it keeps the impedance constant at 50R regardless of frequency (RD06HHF is about 200R).
