“…The active load-pull technique is a technique in which the desired load reflection coefficient is achieved by actively injecting the signal at the output port of the device under test (DUT). Most of the developed active load-pull approaches can be grouped into two, namely active open-loop [3,12] and active closed-loop [4] techniques. In the active openloop load-pull technique, the injected signal, a 2 , is produced through an external signal generator and is independent of the transmitted signal, b 2 .…”

This paper presents a robust heterodyne mode of operation for the envelope load-pull system. Extensive performance evaluation and verification demonstrate the reliable, flexible and accurate nature of the system. The new system was compared with the active open-loop load pull, with the new system standing out as having superior performance in terms of measurement throughput, thereby improving the yield and turn-around in the design of power amplifiers. Finally, measurements on commercially available microwave transistor devices show some of the immediate recognized application areas of the developed system.
