Where in the states can i purchase germanium 1N23 diodes?


First off, as far as I know, they're silicon. And they come in a
microwave package that is meant to be inserted into a waveguide, to be
used as a detector. Are you sure this is what you want?

Most UHF diodes such as the 1N5711 schottky diode would work okay for
detecting RF or whatever. Easier than using a 1N23.


With a two digit number after the '1N'? They're Germanium point-contact
diodes, used in some (if not all) WWII radar sets.

And with that package, if it's what you need it's all that'll do, unless
there's a hot-carrier diode that's been made to be compatible.

If only 1N23 will do, try American Microsemiconductor in the States.
Dial Electronics in the UK list 1N23, 1N23A, 1N23B, 1N23BM, 1N23BMR,
1N23BR, 1N23C, 1N23CR, 1N23D, 1N23DR, 1N23E, 1N23EC, 1N23EMR, 1N23ER,
1N23F, 1N23FMR, 1N23G, 1N23GR, 1N23H, 1N23R, 1N23WE, 1N23WFM, 1N23WG,
and 1N23WGMR and call them S-X Band Point-Contact Mixer Diodes.

Otherwise you may consider a HP2835 Schottky ("hot-carrier") diode
(actually a Hewlett-Packard 5082-2835), it comes in a small glass
package and generally rectifies better than germanium diodes.
