Hi-Q W-Band Ultra Low Phase Noise Analyzer

HI-Q® W-Band phase noise test system utilizes
microwave photonics techniques for automated
measurement of ultra-low phase noise W-band

HI-Q® W-Band Phase Noise Analyzer is fast and fully automated and yields the spectral density of the phase noise of a millimeter wave signal source or amplifier at any operating frequency within the specified band.


This homodyne-based system is unique in wide frequency band measurement without requiring external low noise reference source or mixer, as required in conventional heterodyne approaches. The system operates with ease, speed, and precision using a simple graphic user interface via a notebook PC. The system offers ultra-low phase noise floor with cross-correlation option among other customizable features and configurations.
