A majority of people now have a digital mobile device whether it be a cell phone, laptop, or blackberry. Now that we have the mobility we want it to be more versatile and dependable; RF power amplifiers accomplish just that. These amplifiers take a small input and make it stronger and larger creating a wider area of use with a more robust signal.Switching mode RF amplifiers have been theoretically possible for decades, but were largely impractical because they distort analog signals until they are unrecognizable. However, distortion is not an issue with digital signals-like those used

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
