Pulling Power [Microwave Bytes]

It is always good to get feedback. I ran into an old colleague recently whom I had not seen for some years. He said he liked my column but wondered whether I had ever considered writing one on a subject that I actually knew something about. Wow, thanks pal, I get your drift. But why not; for the first time in living memory I will write about RF power amplifiers (RFPAs), rather than sliding into the subject towards the end, which seems to happen more often than not.
