Does anyone know of a source for a couple of 1N23W mixer diodes?

This is not a new design, they are for repair. So, I must use the old
style cartridge unit.

Thanks!

No help, probably, but most early marine radars used the type diode
you
are looking for, usually in a matched pair (one reverse polarity from
the
other). A most common replacement, and which worked as well or better
was
the 1N415E (or F too, if I remember correctly) The 415's cap could be
installed on either end for reversing the polarity.
Both the 23 and the 415 types are very sensitive to damage from
external RF fields and static electricity. Came packed in metal tubes,
metal
foil or other RF protecting packaging. If your use is very critical, try
to
avoid buying any not in original, unopened packaging.
But you probably already know all of that...... grin!

Some were packed in lead foil, as well.


I have two of them indeed packed in lead tubing.
