Abstract

This paper addresses nonlinear distortion arising in microwave band-pass memoryless and dynamic systems, focusing on wideband power amplifiers (PA). It first identifies the minimum requirements for their correct representation. Then, it shows that the complex behavior of long term memory effects does not allow a unique characterization procedure, but requires various nonlinear distortion figures according to the type of nonlinear RF impairments the actual system is sensitive to.
