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. The introductory Chapter 1 describes the basic principles of power amplifier design procedures. Based on the spectral-domain analysis, the concept of a conduction angle is introduced with simple and clear analyses of the basic Class A-, AB-, B- and C-power amplifiers. In Chapter 2, the voltage-switching and current-switching configurations of Class D-power amplifiers are presented, the increased efficiency of which is a result of operating the active devices as switches. Chapter 3 describes the different Class-F techniques using lumped and transmission line elements, including a quarter-wave transmission line. Chapter 4 describes the different inverse Class-F techniques using lumped and transmission line elements, including a quarter-wave transmission line. Chapter 5 presents the historical aspects and modern trends of Class-E power amplifier design. In Chapter 6, the switchmode second-order Class-E configurations with one capacitor and one inductor and generalized load network, including the finite DC-feed inductance, shunt capacitance and series reactance, are discussed and analyzed. Chapter 7 presents the results of exact time-domain analysis of the switched-mode tuned, Class-E power amplifiers, with a quarter-wave transmission line. Chapter 8 offers alternative and mixed-mode configurations of high-efficiency power amplifiers. Chapter 9 focuses on five CAD programs for analyzing the time-domain and frequency-domain behavior of the switched-mode high-efficiency power amplifiers in frequency ranges from high frequencies to microwaves.

Classic Works in RF Engineering, Volume 2: Microwave and RF Filters
Ralph Levy, Editor
Artech House • 418 pages; $129, £61
ISBN: 978-1-59693-212-8
The object of this book is to present the reader with a selection of the many papers on RF and microwave filters that is most relevant to the requirements that exist today. Some early papers, considered to be breakthroughs at the time they were published, are not included if they have become superseded by later work. The reprints are grouped in ten categories, each one preceded by an introduction giving an overview of the particular class of filters in a given category. Chapter 1 is concerned with basic bandpass filters of the simple Chebyshev or Butterworth type. Modern filter design relies to a considerable extent on so-called transformedvariable synthesis, which is the subject of Chapter 2. Chapter 3 is devoted to crosscoupled and pseudo-elliptic filters. Chapter 4 describes parallel-coupled line, hair-pin-line and microstrip bandpass filters. Chapter 5 is concerned with dielectric-resonator filters, which are used for two purposes: to reduce the size of filter cavities and to increase the unloaded Q, resulting in much lower loss. Bandstop filters are the subject of Chapter 6, while Chapter 7 is concerned with low pass filters. Suspended substrate stripline filters are described in Chapter 8. It is not always realized that lumped element filters may be built to operate at frequencies up to 18 GHz. Chapter 9 offers examples of this kind of filter. Chapter 10 comprises papers on power handling, insertion loss, group delay and tuning.
