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 11970Q 33 to 50 GHz 11970V 50 to 75 GHz
11970A 26.5 to 40 GHz 11970U 40 to 60 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.

Frequency extension for the Keysight N9030A
PXA Series signal analyzer
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
