Power amplifiers guzzle power. At a time when there is considerable pressure to be more green and to reduce the costs of a system by developing technologies that are energy efficient, this book is particularly relevant because it focuses on energy efficient amplifiers, namely, switch mode amplifiers. These amplifiers are at the heart of cellular/wireless communications systems, being used for the transmitter but are also widely used for satellite and radar communications. This book gives engineers all they need to know to use RF and microwave power amplifiers, balancing theory with practica
