Long time listener, first time caller here.

Does anyone have recommended sources for aerospace quality solid state
power amplifiers ( between 1 to 2 kW peak power output range, center
frequency above 2 Ghz, < 0.7 kg, Qty 4 )? Our company has been having
difficulty getting quotes. We were initially looking outside the latest
greater east asia co-prosperity sphere, but maybe we shouldn't be so
picky and just look for something with a commercial rating and do some
extensive testing or ask for modifications with extended temperature
range parts.

Pointers or advice on the above would be appreciated.

I wonder if there is any such thing. Did you find anything with similar
specs?

Yes, we had two vendors respond, one with a semi-reasonable quote, the
other being more than triple that number. After project delays due to
our not getting funding on time, the semi-reasonable vendor subsequently
has withdrawn their quote. This may bust the budget on our subsequent
funding request. Perhaps there's someone out there who has done some
S-band RF work and may know other vendors with this capability.

Sounds like a lot of juice for that frequency. Less than a kg in
weight? Sure... bare board maybe. Not an enclosed product.

That is a lot of power for that weight spec.

You got it.

We have a phase change material heat sink and heat pipe connection to
the radiators.

2kW at 2GHz under 700g? In space, with no cooling airflow, I presume?
I certainly raised my eyebrows.

I've got a few leads now. Thanks to everyone who responded.

If anyone thinks of another option, feel free to post here or reply via
