RF Power Amplifiers

This book is about RF power amplifiers used in wireless communications and many other RF applications. It is intended as a concept-oriented textbook at the senior and graduate levels for students majoring in electrical engineering, as well as a reference for practicing engineers in the area of RF power electronics. The purpose of the book is to provide foundations for RF power amplifiers, efficiency improvement, and linearization techniques. Class A, B, C, D, E, DE, and F RF power amplifiers are analyzed and design procedures are given. Impedance transformation is covered. Various linearization techniques are explored, such as predistortion, feedforward, and negative feedback techniques. Efficiency improvement methods are also studied, such as envelope elimination and restoration, envelope tracking, Doherty amplifier, and outphasing techniques. Integrated inductors are also studied.
