Specifications

Specifications for the 11970 Series Mixers are listed in Table 1-1. These are the performance standards against which the mixers are tested (performance tests are provided in Chapter 3 ,“Performance Tests,”). Typical or nominal operating values are listed in Table 1-2.

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.

NOTE

See Chapter 4 ,“Service,” for a list of replacement parts.
