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 practical examples of implementation, enabling them to understand design issues and trade-offs and improve their future designs.

*Unique focus on switchmode RF and microwave power amplifiers that are widely used in cellular/wireless, satellite and radar communication systems and which offer major power consumption savings

*Complete coverage of the new Doherty architecture which offers major efficiencies and savings on power consumption

*Balances theory with practical implementatation, avoiding a cookbook approach, enabling engineers to develop better designs

*Trusted content from leading figures in the field with a Foreword of endorsement by Zoya Popovic
