This paper examines the application of a broadband modulated measurement system, and specifically how such a system can be used in combination with active IF load-pull in order to characterize a device whilst operating in an Auxiliary Envelope Tracking (AET). The AET modifies dynamically the instantaneous DC applied to the device through the optimization of baseband impedance. The experimental measurements are carried out on a GaN HEMTs device to investigate the idea of improving the linearity of the device using the very mechanism that is employed to improve efficiency of the device. The investigations have shown a significant improvement in linearity of the device
