Hi
As part of your “simple replacement” … keep in mind that it needs to act
both as a multiplier *and* as a mixer. The two modes need to be reasonably
separate from each other or you (likely) get a real mess.

Disassembled the surplus Rx cell by first disconnecting
the short jumper cable and then unscrewed the brass
part. Inside was a tiny diode, color coded "391"
as have been previously discussed in a thread some years ago.
I recon that if a diode would some time in the future breakan external

Thanks for the picture. The small coax link cable is even more brown
than the one i my cavity
I did realize that it should be possible to test the diode
using a 20k/V resistance meter. There has been no more "hick-ups"
and what the cause was is unknown, but many repair sessionscan of
Hi
The SRD is not easily accessible. Digging in to get it is going to
involve a bit of work.
The power level is going going to be a function of the cavity design.
Apparently that design is “non-standard” so any number will be a guess.
The 5065 manual shows typical RF voltage levels into the cav
I see.
Is the SRD in the Rx module accessible at all?
What type of package is it? Is it possible
to dismantle the Rx unit without risk of cracking
the glass enevlope?
Does anybody know the power level at 6 GHz?
