Hi,
I was tasked to research on the possibility of making a ultra wideband high power amplifier. BW is 2-20GHz @ 1000w Output CW,
I've been researching on some power amplifiers manufactures, and the highest PA i saw was 30w at the same freq range (Bonn Elektronik). So I'm guessing this isn't available commercially.
Then I found some books and papers pointing to the direction of using some pre-amp, power splitter, HPAs, and then power combiner to achieve good BW and high power, but high power wideband splitters/combiners seems kinda hard to find as well.
So far I know TWTAs are probably the way to go for the ultra wideband HPA since Solid States in general doesn't produce that high of power. Wilkinson or Radical might be the choice for splitter/combiner, but I haven't found anything promising yet.
So I'm wondering if anyone can point me to a good direction of researching by telling me what types of topologies for HPA and splitter/combiner could reach such requirements.
Thanks!
