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
and PSA Series spectrum analyzers
The 11970 Series harmonic mixers are fully compatible
with the Agilent E4407B, 8560E/EC Series, 8566B (requires
a preamplifier), 71000, and PSA 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.
Frequency extension for the Agilent
N9030A PXA Series signal analyzer
The 11970 Series harmonic mixers (11970K excluded)
are also compatible with the N9030A PXA Series high-
performance signal analyzer. The PXA offers optional
external mixing (Option EXM), enabling it to work with
the 11970 Series and other external mixers for frequency
extension. An external diplexer is required because the
PXA external mixing has a single SMA LO/IF port, whereas
the 11970 Series mixers have separate LO and IF ports.
Recommended diplexers can be purchased from Agilent
as N9020A-E13, or from OML Inc. as DLP.313B.
