Wenzel has published the schematic of an excellent squaring circuit. I
don't have the URL for their version handy, but I used it (with a couple
of mods) in the TADD-2 and TADD-2 Mini designs. You can see the
schematic in the T2-Mini users guide at
http://www.tapr.org/~n8ur/T2_Mini_Manual.pdf.
It will square up signals as low as -20dBm with very low jitter, and
provides a TTL-compatible output.

Hi Rick:
Any suggestions for a circuit with better performance. Purpose will be a
external standard for a frequency counter.

This is a comparator based circuit. This will give
you worse performance than just about anything else,
but it may be good enough anyway.
