Abstract
Many radio frequency (RF) power amplifiers (PAs) behavioral models have been developed in the past decades. Typical among them are Wiener model, Hammerstein model, Wiener-Hammerstein model, memory polynomial model, Volterra-based model, neural networks model. All these models have become powerful tools in modeling the RF PAs and the PAs linearization. Yet their formulations appear to be unrelated. We use memory polynomial and Volterra series to generalize all these different behavioral models. The significance of this paper is twofold: 1) all the RF PAs behavioral models can be unified by memory polynomial and Volterra series and 2) any other new models may be developed with memory polynomial and Volterra series framework.
