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.

Millimeter wave active load pull using low frequency phase and amplitude tuning

A load pull system and method for calibrating the system and conducting measurements on a Device Under Test (DUT). The system includes at least one passive tuner; and a modulated signal connected to the DUT input. The passive tuner is calibrated at multiple frequencies within the modulation bandwidth of the modulated signal. The impedance and measured quantities such as power at the DUT reference plane are determined using tuner s-parameters at multiple frequencies within the modulation bandwidth.
