Abstract :
Knowledge of device input impedance as a function of power level and load matching is useful to fully understand non-linear device behavior, and is also needed to rigorously determine the delivered input power for any arbitrary source tuner setting. This paper describes a technique of measuring the input impedance directly during a load or source pull using a vector network analyzer.
