Hello all,

I want to try to detect signal levels of 50mv to 200mv peak to peak.
I need a passive circuit with no amplifiers, and I will be feeding a
DVM with .01v resolution. The problem I am having is that a 1N34 will
not conduct very well at these low levels. Is there a more suitable
diode? Can you give me a part number, or a simple way to get just one
or two of these diodes? What the diode is looking at is a 50 ohm port
on a 30 to 60 mhz I.F. chassis.

This might be useful:
