Specifications for the 11970 Series Mixers are listed in
standards against which the mixers are tested (performance tests are provided in
). Typical or nominal operating values are listed in

NOTE
Supplemental characteristics are included only as additional information;
they are not specifications.
Equipment Supplied
Waveguide Connector Screws
Five hex-head screws are supplied with each mixer. Four are required to make the mixer-to-waveguide
connection, one is a spare. Use ONLY the screws supplied to attach the mixer to the waveguide. Because
of slight differences in the way the mixers couple with the waveguide, the square-flange mixers (11970K
and 11970A) and the round-flange mixer (1970Q, 11970U, 11970V and 11970W) require different
screws.
If your mixer has a square waveguide flange, use four hex-head screws with Part Number
3030-0221. If it has a round waveguide flange, use four hex-head captive screws with Part
Number 1390-0671. The special balldriver hex screwdriver available in the Option 009
Mixer Connector Kit simplifies installation of the waveguide connector screws.
