If you are an engineer or RF designer working with wireless transmitter power amplifier models, this comprehensive and up-to-date review of nonlinear theory and power amplifier modeling techniques is an absolute must-have. Including a detailed treatment of nonlinear theory, as well as chapters on memory effects, implementation in commercial circuit simulators, and validation, this one-stop reference makes power amplifier modeling more accessible by connecting the mathematics with the practicalities of RF power amplifier design. Uniquely, the book explains how systematically to evaluate a model's accuracy and validity, compares model types and offers recommendations as to which model to use in which situation.
