This book clarifies RF theory and provides practical applications in developing RF/microwave circuits for wireless applications. The book discusses the RF circuit blocks in wireless applications, including amplifiers, mixers, oscillators and frequency synthesizers.

Chapter 1 is an introduction to digital modulation, the foundation of most wireless communications systems, and its performance evaluation. A survey of current ICs used in wireless applications is also included. Chapter 2 is a comprehensive introduction to the various semiconductor technologies and their characteristics in wireless applications. In addition to linear performance of semiconductors, their non-linear behavior is also examined, as well as details on parameter extraction. Chapter 3 provides a detailed analysis of discrete and integrated amplifiers, providing insight into semiconductor performance and circuitry necessary to derive optimum performance from the devices. Properties such as gain stability and matching are covered, and one-, two- and three-stage amplifiers with internal DC coupling and feedback often found in ICs, are described.

Chapter 4 is a detailed analysis of available mixer circuits that are applicable to the wireless frequency range. Insight is provided into the differences between passive and active mixers, and additive and multiplicative mixers. Chapter 5 deals with oscillators, covering the necessary conditions for oscillation and the resulting phase noise for various configurations. Microwave oscillators and ceramic resonator configurations are covered.

Chapter 6 deals with frequency synthesizers, and synthesizer components, such as loop filters, and phase/frequency discriminators, are examined. The principles of direct digital frequency synthesis, as well as fractional-N division synthesis are covered.

The Appendices cover an approach to high frequency modeling and integrated parameter extraction for HBTs, a CAD-based application for determining circuit performance, and an electronic reproduction of a manual for a GSM handset application board that can be downloaded via the Web.

This book covers various aspects of microstrip antennas, including analysis techniques, prominent antenna types, circularly polarized antennas, loaded and active antennas, broad-banding techniques and array antennas. Antenna types covered include rectangular, circular and triangular patches, dipoles and slots.

Chapter 1 is an introduction to microstrip antennas, describing their advantages and limitations, and their major applications in communications and radar. A comparison of the various feeding techniques, radiation mechanisms, and evaluation of radiation fields and surface waves is presented. Chapter 2 deals with the analytical models for microstrip antenna analysis, including models for simple transmission line and cavity models and the lossy transmission line model.

Chapters 4 and 5 cover rectangular and circular microstrip antennas, respectively. All aspects of the antenna designs are considered, culminating in CAD techniques. Chapter 6 deals with dipoles and the triangular microstrip patch antenna. Analysis of the equilateral triangular microstrip patch antenna, famous for its circular polarization, is offered.

Microstrip slot antennas are discussed in Chapter 7, including the most famous slot antenna, the tapered slot and the annular slot versions. Chapter 8 covers circularly polarized microstrip antennas, including single fed and dual-orthogonal fed types. Chapter 9 describes techniques for broad-banding microstrip antennas, including the proper choice of substrate, proper feeding techniques, impedance matching and multiple-mode excitation techniques. Compact designs are the subject of Chapter 10. Loading is discussed along with dual frequency operation, polarization control, radiation pattern control and frequency agility. Chapter 11 covers active antenna designs and the final chapter describes microstrip antenna arrays.
