11974 Series Preselected Millimeter Mixers
Eliminate the need for signal identification at millimeter frequencies.
The Agilent 11974 series mixers are preselected from 26.5 to 75 GHz
for faster, easier testing of millimeter devices and systems. Pre-
selection reduces mixer overload from broadband signals and reduces
radiation of local oscillator harmonics back to the device under test.
Equipment operators can quickly locate true signals, and software
development for automated measurements is greatly simplified.
These mixers feature advanced barium-ferrite technology and
come with a standalone power supply. They are particularly useful
for broadband millimeter signal analysis, millimeter electromagnet-
ic interference (EMI) measurements, and unattended monitoring of
millimeter signals.
11974 series preselected mixers are available in four bands

Specifications apply when connected to the PSA, 8566B or 70000 series spectrum analyzers.
Compatibility
Upgrade kits are available to assure the compatibility of PSA Series
(E4440A/47A/46A/48A) and ESA (E4407B). Consult your Agilent
sales representative to determine requirements. All 8560EC series,
PSA (E4440A/47A/46A/48A), and ESA (E4407B) spectrum analyz-
ers and the 70907B external mixer interface modules are fully com-
patible with the 11974 series.
11970 Series Harmonic Mixers
The 11970 series waveguide mixers are general-purpose harmonic
mixers. They employ a dual-diode design to achieve flat-frequency
response and low conversion loss. These are achieved without exter-
nal dc bias or tuning stubs. Manual operation and computer-
controlled hardware operation are simplified because mixer bias
and tuning adjustments are not required.
11970 series harmonic mixers are available in six bands (15 to 17 dBm LO)

Frequency response of the mixers is reduced by 1 dB for LO range of 14 to 18 dBm.
Compatibility
The 11970 series mixers extend the frequency range of the PSA
Series (E4440A/47A/46A/48A) high-performance spectrum analyz-
ers, the 8560EC series portable spectrum analyzers, ESA (E4407B)
portable mid-performance spectrum analyzers, the 8566B
spectrum analyzer (used with the 11975A amplifier), and the
70000 modular measurement system (used with the 70907A/B
external mixer interface modules).
