HP 11970, 11974 Series Mixers
HP 11974 Series Preselected Millimeter Mixers
Eliminate the need for signal identification at millimeter frequencies.
The HP 11974 series mixers are preselected from 26.5 to 75 GHz for
faster, easier testing of millimeter devices and systems. Preselection
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 electromagnetic-
interference (EMI) measurements, and unattended monitoring of
millimeter signals.
HP 11974 series preselected mixers are available in four bands

analyzers.
Compatibility
Upgrade kits are available to assure the compatibility of HP 8566A/B
spectrum analyzers and the HP 70907A external mixer interface mod-
ule. Consult your HP sales representative to determine requirements.
All HP 8560 E-series spectrum analyzers and the HP 70907B external
mixer interface modules are fully compatible with the HP 11974 series.

HP 11970 Series Harmonic Mixers
The HP 11970 series waveguide mixers are general-purpose harmonic
mixers. They employ a dual-diode design to achieve flat-frequency re-
sponse and low conversion loss. These are achieved without external dc
bias or tuning stubs. Manual operation and computer-controlled hard-
ware operation are simplified because mixer bias and tuning adjust-
ments are not required.
HP 11970 series harmonic mixers are available in six bands

Compatibility
The HP 11970 series mixers extend the frequency range of the HP 8560
E-series portable spectrum analyzers, of the HP 8566B spectrum analyzer
(used with the HP 11975A amplifier) and of the HP 70000 modular mea-
surement system (used with the HP 70907A/B external mixer inter-
face modules).
