Abstract: A heterodyne, wideband active load pull tuner allows creating and controlling the reflection in a different frequency range than the operation frequency. It comprises an active feedback loop and a digital electronic tuner, wherein the electronic tuner operates at a single frequency while the active loop is wideband.

This, two-frequency operation bypasses all circulator and electronic tuner bandwidth limitations and uses readily available large band components such as mixers and amplifiers.
