Abstract :
In this paper, we present a mixer-like microwave power amplifier (PA) characterization applicable to dynamically biased PAs. This approach takes into account the dynamic dependency of the PA with respect to the varying voltage supply and allows for modeling the up-conversion at the RF output, as well as the dynamically varying bias current. As case study, a hybrid GaAs microwave power amplifier is considered.
