  • Millimeter Wave Measurement

LOS GATOS, Calif., March 14, 2011 — SA Photonics has developed a millimeter wave measurement system (MWMS), a high-power measurement and calibration system that tests and calibrates millimeter wave sources and instrument test ranges. It records power densities in frequencies ranging from 40 to 110 GHz with an accuracy of ±0.5 dB.

MWMS measures millimeter wave emissions directly from their source, providing operators with accurate and timely information about power and frequency. It has applicability to 95-GHz active denial systems. The company says that, as the use of active denial systems for nonlethal applications grows, defense and homeland security agencies will need MWMS to effectively calibrate these systems and ensure their safe use.

MWMS is a next-generation system consisting of a photonic probe and a sophisticated processing unit, a fiber optic spool and up to 5 km of fiber optic cable. The photonic probe relays millimeter wave measurements to the remote processing unit for characterization. Power density and frequency measurements are displayed on the processing unit. The probe, with a minimal 1-cm2 metallic aperture that has little to no effect on field measurements, can withstand millimeter wave power levels in excess of 100 W/cm2.

The turnkey polarization-insensitive system requires no additional hardware and features a touch-screen display with an intuitive graphical user interface. Measurement dynamic range is >50 dB.
