Switchmode RF and Microwave Power Amplifiers, 2nd Edition

Preface

The main objective of this book is to present all relevant information required to design high efficiency RF and microwave power amplifiers, including well-known and novel theoretical approaches and practical design techniques. Regardless of the different operation classes like Class D, Class E, or Class F and their combination, an efficiency improvement is achieved by providing the nonlinear operation conditions when an active device can subsequently operate in pinch-off, active and saturation regions resulting in nonsinusoidal collector current and voltage waveforms, for example, symmetrical for Class-F and asymmetrical for Class-E modes. As a result, the power amplifiers operated in Class F can be analyzed explicitly in the frequency ...
