General Information
Introduction
Introduction
The Agilent Models 11970K, 11970A, 11970Q, 11970U, 11970V and 11970W are general-purpose
harmonic mixers with very flat frequency response characteristics and low conversion loss. Collectively,
they cover the frequency range of 18 to 110 GHz. The 11970K covers the 18 - 26. 5 GHz range; the
11970A, the 26.5 - 40 GHz range; the 11970Q, the 33 - 50 GHz range; the 11970U, the 40 - 60 GHz
range; the 11970V, the 50 - 75 GHz range; and the 11970W, the 75 - 110 GHz range.
The overall local oscillator (LO) frequency range of the 11970 Series Mixers is 3.0 to 6.1 GHz. Each of
the mixers employs a different LO harmonic, and as a result has a different optimum LO range within the
overall LO range of the series.
An 8 1/2 by 11 inch conversion losss table and chart is included with each mixer shippment. There is also
electronic media included that is used to download the conversion loss data into a few of the Spectrum
Analyzers documented in this user’s guide. This conversion loss data table must be employed for
absolute amplitude measurements. Also supplied with each mixer are five screws (four required) for
attaching the mixer RF input flange to the waveguide.
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 (11970Q, 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 3 , “Service.” for a list of replacement parts.
Mixers Covered by Manual
Serial Numbers
Attached to your mixer is a label, which shows both the mixer model number and its serial number (two
parts). The first four digits and the letter of the serial number are the serial number prefix; the last five
digits are the suffix. The contents of this manual apply to mixers with the serial number prefixes listed
under “Serial Number Prefixes” on the title page of this manual.

11970 Series Harmonic Mixers
Figure 1-1
Options
Option 009, shown in Figure 1-2 on page 12, is a Mixer Connection Kit. It includes three low-loss SMA
cables (Part Number 5061-5458), one hex-head balldriver (Part Number 8710-1539) for tightening the
waveguide connector screws, and one 5/16-inch open-end wrench (Part Number 8710-0510) for use on
the SMA connectors.
Spectrum Analyzer Retrofit Requirements
• N9030A Signal Analyzer
— A Diplexer is required since the N9030A has a single SMA external mixer port, and the 11970
series mixers have separate LO and IF ports. The recommended diplexer can be purchased from
Agilent as p/n N9029AE13 or from OML Inc. as p/n DPL.313B.
— Requires Option EXM
To retrofit Option EXM:
oRetrofit kits (N9030AK-EXM) are only available for N9030A with Option 550, 544, or 543.
oAt this time, you cannot retrofit instruments with Option 503, 508, 513, or 526.
— Software revision must be A.08.01 or later
— The N9030A does not support the 11970K (LO range limitation).
• PSA Series E4440A, E4446A, and E4448A spectrum analyzers require Option AYZ (LO OUT and
IF IN connectors). The E4443A and E4445A do not support external mixing.
• 856x Series portable spectrum analyzers with options 002 (tracking generator) and 327 (no IF IN on
front panel) do not have external mixing capability.

12
General Information
Introduction
• 856x Series Portable Spectrum Analyzers require option 008, or FW date code ≤920528, for signal
identification functionality.
• Agilent E4407B spectrum analyzers require option AYZ (LO Out and IF IN connections).
• MMS analyzers using 11970 series mixers must have a front end model 70907A, 70907B, 70909A,
or 70910A, as well as a 70900A/B with firmware new enough for those modules:
• The 11970 Series Mixers are fully compatible with all 8566B Spectrum Analyzers.

Maximum Shock: 30 G's
NOTE Unless otherwise stated, all specifications apply for an IF range of 300 to 322.5
MHz as required by the various spectrum analyzers covered in this user’s guide.
Also, the specifications only apply with RF input levels of less than −20 dBm.
