Résumé

Here is a thorough treatment of distortion in RF power amplifiers. This unique resource offers expert guidance in designing easily linearizable systems that have low memory effects. It offers you a detailed understanding of how the matching impedances of a power amplifier and other RF circuits can be tuned to minimize overall distortion. What's more, you see how to build models that can be used for distortion simulations.

A new measurement methodology enables you to gauge the amplitude and phase of distortion components and recognize memory effects. The book explains that by killing memory effects, it is possible to use simple linearizers, such as analog predistortion, and still achieve sufficient performance. You learn a distortion analysis technique that allows you to repeat the analysis with other amplifier structures. Including over 120 equations and more than 110 illustrations, this practical reference provides you with the assistance you need to create amplifiers suitable for linear transmitters, and offers you new views of semiconductor modeling.
