Exceptional performance
The Keysight Technologies, Inc. 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
11970U
33 to 50 GHz
40 to 60 GHz
11970V
11970W
50 to 75 GHz
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.
* 11970K is excluded from PXA support
03 | Keysight | 11970 Series Harmonic Mixers - Data Sheet
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.
Frequency extension for the Kaysight E4407B,
8560E/EC Series, 8566B, and 71000 Series
and PSA Series spectrum analyzers
The 11970 Series harmonic mixers are fully compatible with the
Keysight 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 Keysight N9030A
PXA Series signal analyzer
Figure 1. The 11970 Series mixers have separate LO input
and IF output ports
The 11970 Series harmonic mixers (11970K excluded) are also
compatible with the N9030A PXA Series highperformance 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 Keysight as
N9029AE13, or from OML Inc. as DLP.313B.
Rugged
The rugged Keysight 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

1. An LO power of between 14.5 to 16 dBm at the mixer’s LO input is necessary to achieve the given frequency response and spectrum analyzer amplitude accuracy specifications. When LO
power varies between 14 to 18 dBm at the mixer’s LO input, add ±1 dB to the frequency response and spectrum analyzer amplitude accuracy specification.

1. When used with 11970 Series mixer in A-, Q-, or V-band, the PXA’s LO harmonics are automatically switched between two different numbers as listed to optimize
conversion loss.
2. If the LO harmonics are switched, the noise levels for the signal analyzer/mixer combination will change, corresponding to the different LO harmonic numbers.
