RF Power Amplifier, 2nd Edition

Preface

The second edition of RF Power Amplifiers is designed to be an improvement, updation, and enlargement of the first edition. 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 edition of this book is a thoroughly revised and expanded version of the first edition. 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 dynamic power supply method, envelope elimination and restoration (EER), envelope tracking (ET), Doherty amplifier, and outphasing techniques. Integrated inductors are discussed as well. RF oscillators are also covered. RF power amplifiers are used as power stages of radio transmitters. Radio transmitters are used in broadcasting systems, mobile wireless communication systems, radars, and satellite communications.
