MMW-STUDIO mmW and Sub-THz characterization software suite is designed to work with a 4-port VNA using waveguide extender modules and add accurate and repeatable high-resolution power control for direct measurement of vector corrected power and s-parameter measurements at the DUT reference plane. The load-pull software add-on combined with a Vector Modulation Unit (VMU), enables users to set arbitrary impedances, or perform active load pull measurements, where the magnitude of reflection presented to the DUT is achieved by controlling the ref a2 wave for maximum smith chart coverage. The industry’s first and only mmW and sub-THz software platform designed for large signal gain compression and active load pull measurements up to 1.1 THz!
