Extension of the hammerstein model for power amplifier applications

This paper presents a novel behavioral model for RF amplifiers with memory. The model is an extension to the well-known Hammerstein model. All identification and verification are done using sampled input and output signals of a power amplifier. The extended Hammerstein model is found to decrease the out-of-band modeling error with as much as 10 dB compared to the Hammerstein model.
