Technologies for RF Systems
This comprehensive resource provides an introduction to the main concepts, technologies, and components in microwave and RF engineering. This book presents details about how to design various amplifiers, circuits, and chips for communication systems. It offers insight into selecting appropriate ADC and DAC technology. Several worked examples are found throughout the book. This book provides a summary of 21st century RF systems and electronics and discusses the challenges of frequency bands and wavelengths, software-defined radio (SDR) and cognitive radio. RF semiconductors are covered, including bandgap, drift velocity, resistors, diodes, and various transistors. This book offers details about passive RF components, capacitors, inductors, resistors, coaxial, and microstrip lines as well as coplanar waveguide. Passive RF circuit elements are presented and this book covers the fundamentals of directional couplers, including Lange couplers and Wilkinson dividers. Switches, attenuators, and digital circuits are discussed. This book is packed with additional coverage of RF filters, antennas, and small-signal RF amplifiers, and includes chapters on noise and LNAs, RF power amplifiers and RF-oriented ADCs and DACs. Modulation techniques and technologies are also presented.

The U.S. Special Operations Command (SOCOM) was formed in response to the failed rescue attempt in 1980 of American hostages held by Iran. Among its key responsibilities, SOCOM plans and synchronizes operations against terrorist networks. Special operations forces (SOF) often operate alone in austere environments with only the items they can carry, which makes equipment size, weight, and power needs especially important. Specialized radios and supporting equipment must be carried by the teams for their radio-frequency (RF) operations. As warfighting demands on SOCOM have intensified, SOCOM's needs for significantly improved radio-frequency (RF) systems have increased. Toward a Universal Radio Frequency System for Special Operations Forces examines the current state of the art for both handheld and manpackable platform-mounted RF systems, and determines which frequencies could be provided by handheld systems. The book also explores whether or not a system that fulfills SOF's unique requirements could be deployed in a reasonable time period. Several recommendations are included to address these and other issues.
