This paper presents a novel solution for the load-pull measurement of highly mismatched power transistors by means of using a broadband impedance transformer. This technique enables the power requirements of active load-pull systems necessary to synthesize load impedances at the device reference plane to be reduced significantly compared to the mismatched system.
