Abstract

An overview of nonlinear response functions in time and frequency domain is given; memory effects are described in this context and dispersion relations are discussed. Disadvantages of standard measurement methods like 1 dB compression and 3rd order intercept points are mentioned and some requirements on more complete characterisation of RF/microwave power amplifiers; desirable for the development and verification of predistorters; are given. Memory effects in inverse nonlinear response functions and their relation to predistortion algorithms are discussed as well as the change in requirements on the TX-chain imposed by digital predistortion.
