The main objective of this book is to present all the relevant information required for RF and microwave power amplifier design, including well-known and novel theoretical approaches and practical design techniques as well as to suggest optimum design approaches effectively combining analytical calculations and computer aided design.

In Chapter 1, the two-port networks are introduced to describe the behavior of linear and nonlinear circuits. The main purpose of Chapter 2 is to present widely used nonlinear circuit design techniques to analyze nonlinear power amplifier circuits. In Chapter 3, all the necessary steps to provide an accurate device modeling procedure, starting with the determination of the small-signal equivalent circuit parameters, are described and discussed. A variety of nonlinear models for MOSFET, MESFET, HEMT and bipolar devices, including HBT, which are very prospective for modern microwave integrated circuits of power amplifiers and oscillators, are presented. A concept of impedance matching and the impedance matching technique, which is very important when designing power amplifiers, is presented in Chapter 4. Chapter 5 describes the basic properties of three- and four-port networks as well as a variety of different combiners, transformers and directional couplers for RF and microwave power applications. Chapter 6 represents the fundamentals of the power amplifier design, which is generally a complicated procedure when it is necessary to provide simultaneously accurate active device modeling, effective impedance matching depending on the technical requirements and operating conditions, stability in operation, and ease in practical implementation. Chapter 7 describes in detail the possible circuit solutions to provide a high efficiency power amplifier operation based on using different overdriven (classes B, F and E) classes of operation or newly developed subclasses, depending on the technical requirements. Chapter 8 describes the power amplifier design based on a broadband concept that provides some advantages when there is no need to tune the resonant circuit parameters. Chapter 9 describes the different approaches to improve linearity and efficiency of the power amplifiers in telecommunication systems

This book is based on recent research work conducted by the authors, dealing with broadband microwave amplifiers for EW, fiber-optic communications and instrumentation applications. It presents broadband amplifier designs through a series of design examples that were realized and characterized. Chapter 1 provides a historical perspective on the most common types of broadband amplifiers and introduces the concept of the cascaded single-stage distributed amplifier (CSSA). In Chapter 2, the principles behind the traveling wave distributed amplifier (TWDA) and the novel CSSA are discussed. In particular, the theory and a comparison between these two types of distributed amplifier architectures are presented. Chapter 3 reviews the structure and the basic operation of GaAs MESFET and single- and double-heterojunction PHEMTs. The latter two devices are shown to be far superior to the conventional GaAs MESFET in terms of providing high frequency performance with substantially improved gain, output power and power-added efficiency. Chapter 4 describes the procedure used for carrying out small-signal and large-signal device characterization, which is essential for obtaining accurate equivalent circuit models for the devices that are used for the design and modeling of the broadband amplifiers. This chapter also describes the procedure for accurately extracting the device’s small-signal and large-signal equivalent circuits from the device’s S-parameter and pulsed I-V measured data. Chapter 5 provides general analyses on the different classes of amplifier operation for broadband applications. Chapter 6 describes the design, analysis, fabrication and measured performance of different types of broadband amplifiers operating across the frequency range of 2 to 18 GHz. Chapter 7 covers the practical aspects of the realization of the broadband amplifier designs of Chapter 6. The fabrication of the broadband amplifiers is implemented using a hybrid MIC technology. Chapter 8 describes the design of ultra broadband microwave amplifiers for data modulator drivers.
