New RF and microwave frequency microelectromechanical systems (MEMS) have potentially enormous and widespread applications in the telecommunication industry. This book sets out the basics of RF MEMS and describes how to design practical devices and circuits. As well as covering fundamentals, it offers expert tips for designers and presents a range of real-world applications. The book is suitable as a tutorial for electrical and computer engineering students, or as an up-to-date reference for practicing circuit engineers. It provides the most comprehensive survey of this new and important technology. In 15 chapters, the author, with the help of seven of his graduate students, covers in detail the MEMS technology available at the present time.

Chapter 1 is an introduction to RF MEMS for microwave applications. The mechanical modeling of MEMS devices is described in Chapters 2 for static analysis and 3 for dynamic analysis. The electromagnetic modeling of MEMS switches is the subject of Chapter 4. Chapter 5 offers an extensive MEMS switch library of devices provided by numerous sources from industry and academia. MEMS fabrication and packaging technologies are introduced in Chapter 6, while Chapter 7 treats MEMS switch reliability and power handling. The designs of MEMS switch circuits, MEMS phase shifters, distributed MEMS phase shifters and switches, MEMS varactors and tunable oscillators, micromachined inductors, reconfigurable MEMS networks, filters and subsystems, are described in Chapters 8 to 13. In Chapter 14, a phase analysis of MEMS circuits, phase shifters and oscillators is provided. Finally, in Chapter 15, a summary of the work accomplished to date is given together with suggestions for future work. Two appendices offer a detailed analysis and measurements of intermodulation distortion and power handling in RF MEMS switches, varactors and tunable filters, as well as a table of mechanical, electrical and thermal properties of RF MEMS materials.

Practical RF Circuit Design for Modern Wireless Systems, Vol. 2: Active Circuits and Systems

This book is the second of two volumes, both of which take a practical approach to RF circuit design. They are the culmination of more than 40 joint years of teaching these topics to thousands of practicing engineers from around the world by the two authors.

Volume 2 focuses on discrete circuits and discrete circuit design rather than IC design, since only when discrete circuit design is mastered can those techniques be applied to integrated circuits. Throughout the book, computer aided design (CAD) techniques are emphasized to encourage the reader to use them as much as possible in his/her daily work. Combining CAD techniques with a thorough understanding of RF fundamentals and the use of traditional engineering tools is the best way to be successful.

Chapter 1 offers some general considerations for linear amplifier design, such as power gain definition, neutralization, unilateral transducer gain, RF circuit stability, stabilization, DC bias techniques and circuit layout considerations. Linear and low noise RF amplifiers are analyzed in detail in Chapter 2. Active RF devices and their modeling are the focus of Chapter 3, and include both diode and two-port RF devices. Nonlinear circuit simulation techniques are the subject of Chapter 4, including analytical methods, time-domain methods, hybrid time- and frequency-domain techniques, as well as the harmonic balance method. High power RF transistor amplifier design is covered in Chapter 5, which introduces nonlinear concepts, the different categories of amplifiers and their comparison, and gives an example of power amplifier design. Oscillators are the topic of Chapter 6, including one-port and two-port oscillators, phase noise characterization and examples of oscillator designs. Chapter 7 considers mixers and frequency multipliers. Finally, circuits in systems and radio system applications are discussed in Chapter 8, including software-defined radios, RF digital processing and an overview of integrated system chips.
