Re: Would you recommend some books for power amplifier desig
most PA stuff at those frequencies can be found in papers and from emprical analysis.
i suggest looking through microwave journal articles (check local university), micrwaves and RF, rf design and so on.
those are the best sources.
also plett/rogers text, radio frequency integrated circuit design is a source as well.
also check these companies app notes:
maury microwave
focus microwaves
if you need more help ask
