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

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

11970Q 33 to 50 GHz

11970U 40 to 60 GHz

11970V 50 to 75 GHz

11970W 75 to 110 GHz

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 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 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 Agilent as N9020A-E13, or from OML Inc. as DLP.313B.

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.
