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...

Robert
