Abstract : pRF power amplifiers PAs used for broadband wireless communication systems such as WCDMA, WiMAX and LTE exhibits a significant amount of dispersion in their amplitude and phase characteristic curves due to memory effects. The conventional Hammerstein model used for modeling RF PAs, characterizes such memory effects very accurately in their linear region and not in their nonlinear region. Hence, to accurately model such dynamic nonlinear characteristics, a new PA behavioral model based on a modified Hammerstein model is used in this article. The enhanced modeling capability of the modified Hammerstein model is validated using a class AB RF Power Amplifier. The results clearly indicate that, the modified Hammerstein model has better modeling performance than the conventional Hammerstein model. © 2018 IEEE./p
