Volume 15 of the MIT RadLab books, "Crystal Rectifiers" 440 pages, is
all about that. History, theory, parts, applications. Appendix D lists
the common mixer types. The history part mentions early mineral-based
rectifiers.

Some interesting sections are one which notes that some diodes have
power gain when used as mixers, and a suggestion that semiconductor
triodes should be possible, and some interesting 100-volt
welded-junction "power" diodes.

Volume 16, "Microwave Mixers" has some more stuff.

These books show up on ebay, or a used-book thing like Alibris.

OK, thanks for the titles, will definitely look for them on eBay or Amazone.
Alibris is new to me, but I'll check.


I think Bliley Corp may have some papers on the history of quartz
crystals. They, along with the point-contact diode, helped to win the
war.

I will definitely try Bliley!

But otherwise, yes, that is one of the important issues I want to document:
to what extent where these components decisive for the outcome of the war.
Interesting stuff, good for the museum expositions I am working on!
