Abstract :
In this paper, the concept of linear and nonlinear memory effects are proposed to explore the internal mechanism of the memory effects. The identification procedure of the linear and nonlinear memory effects is discussed in details. Finally the experimental validation results demonstrate that the nonlinear memory effects are significant for wideband RF power amplifier and cannot be ignored.
