Design of amplifiers and oscillators by the S-parameter method

This book presents a modern approach to the design of amplifier and oscillator circuits. While many electronics firms now depend on scattering-parameter designs in their product lines, there has been no single reference source to the fundamentals, tools, and applications of the S-parameter method. This book serves practicing designers as a working guide to S-parameter design, with emphasis on impedance-matching techniques that do not require the use of a computer. The book's sections cover basic concepts and tools, amplifier designs, and oscillator designs. The first chapter introduces S-parameter two-port network theory and the definitions of power gain. Chapter Two describes microwave transistors, microstriplines, and impedance-matching techniques. This chapter includes a brief description of the most important threeterminal microwave transistors, the silicon bipolar transistor, and the GaAs MESFET Following this introduction, the book discusses actual designs and design problems. Chapter Three is devoted to amplifier designs, including the special considerations of balanced-amplifiers, high-power, broadband-amplifiers, feedback, and two-stage-amplifier designs. Basic limitations in device and circuit performance are discussed for each design. The final chapter deals with oscillator design, introducing the compressed Smith Chart and the application of S-parameters to oscillator circuits. Low-noise, high-power, broadband, and buffered oscillator design considerations are treated in this chapter. Design of Amplifiers and Oscillators By The S-Parameter Method will help the thinking of the design engineer who is using computer-aided design, which can be a risky, expensive solution to a poorly understood design problem. Engineers will find it a source of practical day-to-day guidance in microwave device and circuit design. Advanced students will find it an outstanding introduction to S-parameter techniques as well as to current microwave components.
