MS2830AAnritsu Co. and OML Inc. introduce a millimeter-wave (mm-wave) solution for spectrum and signal analysis of emerging wideband communications systems. The Anritsu MS2830A Signal Analyzer, when coupled with the OML MxxHWD harmonic mixer, offers mm-wave frequency coverage from 26.5 to 325 GHz. Using these new capabilities, engineers can evaluate, characterize and manufacture products designed for emerging wideband standards, such as WiGig, including FCC Part 15 compliance emission testing requirements from 40 to 200 GHz.

The MS2830A has an external mixer design that achieves dynamic range. Utilizing an intermediate frequency (IF) of 1.875 GHz (IF output with 1 GHz bandwidth) and LO range of 5 to 10 GHz, the MS2830A can reduce the multiplier magnitude necessary for mm-wave coverage. Lower multipliers improve the conversion loss of the external mixer, which increases the MS2830A’s sensitivity, allowing the signal analyzer to measure low-level mm-wave signals. Using this configuration, the MS2830A can measure E-band (60 to 90 GHz, WR-12) with better DANL (nominal -120 dBm/Hz @ 80 GHz) based on typical external mixer conversion loss of 36 dB, which represents a minimum 4-8 dB improvement over existing solutions.

“OML delivers the innovative harmonic mixer technology that uniquely qualifies it for plug-and-play compatibility with our external mixer capabilities. The combined solution offers unprecedented capabilities that engineers can utilize to advance wideband communications systems,” said Wade Hulon, Vice President and General Manager, Anritsu Americas.

“With the MS2830A, Anritsu offers outstanding performance, as well as innovative modulation capabilities that mm-wave engineers will appreciate to analyze emerging signals. This new mm-wave solution demonstrates our commitment to deliver innovative instrumentation for next-generation applications,” said Yuenie Lau, Vice President of Operations, OML.

The MxxHWD harmonic mixer, based on a single diode design, is available in waveguide bands from 26.5 to 325 GHz. The harmonic mixer is a two-port frequency extension product with a mm-wave interface for DUT connection and RF interface for LO/IF connectivity with the signal analyzer. The mm-wave connection is compatible with MIL-DTL-3922/67D (UG387/U-M) waveguide flanges. Additional bias features can further optimize signal levels, including flatness.

The MS2830A includes a high-performance, low-cost spectrum analyzer function for measuring up to 325 GHz using an external mixer, such as the MxxHWD. The MS2830A has five different models from 3.6 to 43 GHz, with two external mixers (26.5 and 43 GHz) for the higher frequency models.
