Joe,
I suggest you try Alpha Microwave. They make a large number of Gunn diode
oscillator modules and assemblies. They make a basic module (called the MSM
1000 if my memory serves - and it has been going fast lately!). This module
includes the oscillator and detector and a few other pieces and should be
perfect for your application. It has the advantage that it already meets the
FCC regulations, something that should save you much trouble. I do not have
Alpha's address at home, but you should have no trouble finding them if your
extensive library contains a Thomas Register or other buyers guide. Good luck.
