Thanks Wofgang and George.
The microwave oscillator is the Frequency-West, Inc Model MS-34M. It was m=
anufactured around 1981. I suspect that it may have a high speed transistor=
. We will look into fixing it as well. We have no schematics.

Jack, do you have a part number for the failed diode?

There are some gunn diodes on ebay.

Does anybody know a good source of microwave oscillators (2.5 - 3.5 GHz) wi=
th frequency tuning capability for at least 10 MHz? We are looking for repl=
acement of our old Gunn diode oscillators used in our microwave cavities ex=
periment. Any suggestions would be appreciated.
