Ultra-High-Sensitivity, Millimeter-Wave Spectrum Analysis – High Performance Waveguide Mixer MA2808A Released


Combining the newly released MA2808A with the MS2830A supports development and production of equipment for both E-band wireless backhaul as well as automobile collision avoidance radar

With the October 28 release of its new High Performance Waveguide Mixer (60 to 90 GHz) MA2808A for the company's popular Signal/Spectrum Analyzer MS2830A, Anritsu Corporation has enhanced its line-up of millimeter-wave measurement solutions.

Combining the newly released MA2808A with the MS2830A in the 26.5 GHz/43 GHz configuration (MS2830A-044/045) supports development and production of equipment for both E-band (70/80 GHz) wireless backhaul as well as automobile collision avoidance radar (77/79 GHz).

The MA2808A combines excellent minimum sensitivity performance with a wide measurement span in an easy-to-use configuration to support millimeter-wave measurements that legacy harmonic-mixer and down-converter methods cannot achieve.

Anritsu expects its new measurement solution to find widespread application in development of devices and equipment for the growing number of millimeter-wave wideband wireless services.

[Development Background]

Automobile radar and wireless backhaul services use millimeter-wave technology. Achieving the high-sensitivity detection of relatively small objects such as pedestrians and automobiles that legacy automobile radar cannot recognize, requires developing 79-GHz wideband radar.

Additionally, the wireless backhaul market using wireless technologies to connect base stations covering small areas (small cells) with Core networks is seeing progressive development of E-band equipment supporting large-capacity communications. Meeting the need for fast, large-capacity mobile communications is expected to require widespread deployment of many small cells in urban areas.

Evaluating automobile-radar and wireless-backhaul equipment requires an easy-to-use solution for accurately measuring the characteristics of millimeter-wave, ultra-wideband Tx signals. Previous measurement methods have suffered problems with large conversion losses as well as the appearance of non-existent ghost signals called image responses.

By developing its new High Performance Waveguide Mixer MA2808A with easy-to-use operation, simple setup, and high sensitivity, Anritsu has finally solved the problems of accurately measuring millimeter-wave, wideband wireless equipment.

[Product Outline]

Connecting the developed MA2808A to the MS2830A-044/045 supports occupied bandwidth, spectrum, Mask, etc., measurements of E-band signals (60 to 90 GHz) with a bandwidth of more than 1 GHz.

The Signal Analyzer/Spectrum Analyzer MS2830A is a precision instrument for developing and manufacturing various wireless communications equipment and devices; any one of five models with different upper frequency options (3.6/6/13.5/26.5/43 GHz) can be selected according to the application.

[Key Features]

  • Excellent P1dB Performance and Minimum Sensitivity
    Combining the MA2808A with the MS2830A-044/045 achieves P1dB performance of better than 0 dBm and a minimum sensitivity of –150 dBm/Hz (meas)* for the world's best-in-class wide dynamic range. As a result, this setup can measure very weak signals that cannot be monitored by legacy measurement systems, and supports design and testing of higher-level millimeter-wave wireless equipment.
  • Eliminates Image Response
    When the MA2808A is used with the MS2830A-044/045 designed to support a high IF of 1.875 GHz, it performs spectrum and Mask measurements of signals with a bandwidth of 1 GHz and displays the results without image-response effects. A new (patent pending) function for extending the measurement span supports measurements up to a bandwidth of 7.5 GHz.
  • Simple Equipment Configuration
    Previously, high-sensitivity measurements in the millimeter-wave band required using a down converter in a complex but limited setup with mixer, spectrum analyzer, expensive microwave signal generator producing the Local signal, and multiplier. In contrast, a simple cable connection between the MA2808A and MS2830A-044/045 makes it easy to configure a system for millimeter-wave spectrum measurements.
  • Easy Measurement
    One press of a button preloads the conversion loss data for the entire frequency range from a USB memory stick provided with the MA2808A into the MS2830A-044/045, automatically correcting measurement results for each frequency.
