Abstract
A load pull system for making measurements on a DUT at millimeter wave frequencies using active tuning. The system uses phase and amplitude control of each signal at low frequency before being upconverted to the millimeter wave measurement frequencies. The measured signals at the DUT plane may be down-converted for measurement with a low frequency analyzer.
