Hi,

I have a faulty Boonton 51013 power sensor, which is a diode based probe
for the 4220 RF milliwattmeters. And one of the two detection diodes is
out. Of course both diodes would probably need to be replaced and full
calibration to be done again; but do you have any idea for a potential
replacement diode, not too difficult to find and working up to 10 or 20GHz
?

Thanks for your ideas. Experiences of 510XX sensors repairs would be also
welcome, as the diodes are packed in a copper film...

Pete, KE9OA, had a section on his website with info on those RF Millivolter
probes. Also, the diodes are still available from Boonton, but they are a
tad
pricey.
