I have a WJ M14 mixer with sma connectors on all three ports. Does anybody
ant data on this mixer? A search on the Internet didn't turn up anything and
I get no response from the company even after using a professional for pay
search service contacted them.

It truly is unfortunate if WJ is now unresponsive; in the '70s and '80s I
often wrote WJ requesting data on many products, including mixers, and
always received a reply with copious amounts of material including
spec sheets, manuals, etc.

How times change...

Leland:
The two links below give minimal information about power level,
frequency, etc...
If you need more, I'd contact Mini-Circuits Labs (Harvie Kaylie, the pres),
for a
suggested substitute, and then go from there.These are good guys to work
with, and
you should get everything you require. I -hate- having an electronic part
that can't
be specd out!

Mike;

Thanks for the links. I don't need a substitute part, I have two of these
mixers I picked up at a fleamarket.

The WJ M14 is marked L for LO and has spec of 4-9 GHZ, RF for RF spec is
4-8 GHz, and I for IF spec is DC-2GHz. Isolation between ports is 30db
typical, loss is 5-6 db, and noise figure is 5-7 db. Is that enough info?
Data from 1989 Watkins Johnson catalog. Tom Wb6iqd

LO and RF ports are rated from 4 to 8GHz, IF port is good from DC to 2GHz.
Noise figure is 5dB, and port to port isolation is 35dB. This dats is from
my purple WJ data book.
