Atec Agilent-11970A User Manual
Exceptional performance
The Agilent Technologies 11970 series harmonic
mixers are general purpose mixers employing a
dual-diode design to achieve very flat frequency
response and low conversion loss. Each mixer is
calibrated across its full band:
11970K, 18 to 26.5 GHz
11970A, 26.5 to 40 GHz
11970Q, 33 to 50 GHz
11970U, 40 to 60 GHz
11970V, 50 to 75 GHz
11970W, 75 to 110 GHz
This series of mixers has been designed for a local
oscillator frequency of 3 to 6.1 GHz. Accurate
absolute amplitude measurements can be made by
using the mixer’s conversion loss calibration chart.
The SWR of the waveguide input is typically 2.2:1
to further minimize measurement uncertainty. The
combination of high gain-compression level and low
conversion loss provides the maximum dynamic
range for measuring input signals.

Easy to use
The excellent frequency response and low conversion loss are achieved without external dc bias or
tuning stubs. Since bias and tuning stubs are not
required, manual operation is simplified, and the
complexity of hardware and software for automatic
systems is greatly reduced. The repeatability of
amplitude measurements is also enhanced. The
dual-diode design of the mixers further simplifies
measurements by suppressing the odd-order harmonics by more than 20 dB, which makes identification of the mixing products easier.
Rugged
The rugged Agilent 11970 Series Mixers will survive input levels up to 100 milliwatts (+20 dBm)
with no damage to the mixer diodes. They will
withstand shocks up to 30 G’s and the vibration
required by MIL-STD 28800C, Type III, Class 3
tests.
Frequency extension for the Agilent E4407B,
8560E/EC Series, 8566B, and 71000 Series
spectrum analyzers
The 11970 Series Harmonic Mixers are fully compatible with the Agilent E4407B, 8560E/EC Series,
8566B, and 71000 Series Spectrum Analyzers.
Accurate frequency and amplitude measurements
are made directly from the spectrum analyzer’s
display after calibration using the mixer’s calibration chart. The 11975A Microwatt Power Amplifier
can be used with the 8566B Spectrum Analyzer to
provide the necessary LO power of 14 to 18 dBm to
the mixers. The 11975A has internal power leveling
to achieve maximum measurement accuracy.
