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

Don't know specifically about your Boonton, but would a diode from the
Avago HSCH-53xx series be useful? Some are rated for use up to
26GHz. They are small, of course, about .006 inches wide and .027
inches long (with leads that could perhaps be cut to yield perhaps .
020 inch net length, if absolutely necessary).

Cheers,
Tom

Thanks Tom.
