The rf systems for linear accelerators or storage rings use electronically variable phase shifters as control elements in feedback loops or to set reference phases. A variety of electronic phase shifters has been described in literature. One desirable feature of these devices is a linear response of the phase shift as a function of their control voltage. This report describes the design of 180° phase shifters at 1300 MHz and 353 MHz using voltage variable capacitance diodes as terminations in transmission lines. The optimization of paramenters is discussed with emphasis on linearity, power handling capability and temperature stability. 9 refs., 9 figs.

This book aims to cover a new emerging need in designing digital phase shifter for modern communication systems. With the advancement of new generation mobile communication systems, directed beams of antenna arrays save a substantial amount of power as well as improve the communication quality. In this regard, beam-forming circuits, such as digital phase shifters (DPS) constitute essential parts of the antenna array systems. Therefore, this book is devoted to the design of digital phase shifters for various communications systems. Nowadays, phase array systems demand compact phase shifters suitable for chip implementation with wide phase-range and broad frequency band. Each chapter of this book is organized as stand-alone in such a way that the reader requires no specific background acquired from the other chapters. For each phase shifter topology introduced in this book, the reader is furnished with explicit design equations to construct the circuit under consideration. Furthermore, design equations are programmed using MATLAB to assess the electrical performance of the phase shifters with ideal and lossy components. MATLAB design programs are given at the and of each chapter as appendices and provided as soft copy on the web page of the book. In chapters 12 and 14, MMIC layouts for the lattice and T-section based DPS are provided for the readers. It is hoped that an interested reader can immediately identifies the “optimum phase shifter topology” for the need under consideration with its estimated electric performance.

The Art of Linear Electronics presents the principal aspects of linear electronics and techniques in linear electronic circuit design. The book provides a wide range of information on the elucidation of the methods and techniques in the design of linear electronic circuits. The text discusses such topics as electronic component symbols and circuit drawing; passive and active semiconductor components; DC and low frequency amplifiers; and the basic effects of feedback. Subjects on frequency response modifying circuits and filters; audio amplifiers; low frequency oscillators and waveform generators; and power supply systems are covered as well. Electronics engineers, and readers with an interest in linear electronics design but with minimal experience in the field will find the book very useful.

The Incremental Phase Shifter evolved as a solution to the problem of adjusting orbiting satellite oscillators to a high degree of precision, which ultimately provides flexibility in the adjustment of precision timing marks from the satellite. The unit is an all electronic, solid state device. It is basically digital and locked to the existing satellite oscillator. The techniques used provide a continuous range of tuning with linear resolution surpassing parts in 10 to the 12th power. (Author).

This book throws a lifeline to designers wading through mounds of antenna array patents looking for the most suitable systems for their projects. Drastically reducing the research time required to locate solutions to the latest challenges in automotive communications, it sorts and systematizes material on cutting-edge antenna arrays that feature multi-element communication systems with enormous potential for the automotive industry. These new systems promise to make driving safer and more efficient, opening up myriad applications, including vehicle-to-vehicle traffic that prevents collisions, automatic toll collection, vehicle location and fine-tuning for cruise control systems. This book’s exhaustive coverage begins with currently deployed systems, frequency ranges and key parameters. It proceeds to examine system geometry, analog and digital beam steering technology (including "smart" beams formed in noisy environments), maximizing signal-to-noise ratios, miniaturization, and base station technology that facilitates in-car connectivity while on the move. An essential guide for technicians working in a fast-developing field, this new volume will be warmly welcomed as a powerful aid in their endeavors.

The aim of this book is to present in one volume some of the most significant developments that have taken place in the field of integrated ferroelectrics during the last decade of the twentieth century. The book begins with a comprehensive introduction to integrated ferroelectrics and follows with fifty-three papers selected by Carlos Paz de Araujo, Orlando Auciello, Ramamoorthy Ramesh, and George W. Taylor. These fifty-three papers were selected from more than one thousand papers published over the last eleven years in the proceedings of the International Symposia on Integrated Ferroelectrics (ISIF). These papers were chosen on the basis that they (a) give a broad view of the advances that have been made and (b) indicate the future direction of research and technological development. Readers who wish for a more in-depth treatment of the subject are encouraged to refer to volumes 1 to 27 of Integrated Ferroelectrics, the main publication vehicle for papers in this field.

This exciting new book focuses on the analysis and design of reconfigurable antennas for modern wireless communications, sensing, and radar. It presents the definitions of basic antenna parameters, an overview of RF switches and explains how to characterize their insertion loss, isolation, and power handling issues. Basic reconfigurable antenna building blocks, such as dipoles, monopoles, patches and slots are described, followed by presentations on frequency reconfigurable antennas, pattern reconfigurable antennas, and basic scanning antenna arrays. Switch biasing in an electromagnetic environment is discussed, as well as simulation strategies of reconfigurable antennas, and MIMO (Multiple Input Multiple Output) reconfigurable antennas. Performance characterization of reconfigurable antennas is also presented. The book provides information for the technical professional to design frequency reconfigurable, pattern reconfigurable, and MIMO antennas all relevant for modern wireless communication systems. Readers learn how to select switching devices, bias them properly, and understand their role in the overall reconfigurable antenna design. The book presents practical experimental implementation issues, including losses due to switches, materials, and EMI (Electromagnetic Interference) and shows how to address those.

A compact one-dimensional fixed phase shifter is presented in this thesis. The proposed phase shifter comprises metamaterial unit cells that consist of a host transmission line loaded with lumped-element capacitors and inductors, arranged in a dual high-pass configuration. Through periodic dispersion analysis, an effective propagation constant is derived, and design equations are presented for determining the lumped-element parameters for an arbitrary phase shift. Various phase shifters are fabricated and tested in coplanar waveguide technology at 0.9 GHz. It is demonstrated that the metamaterial phase shifters offer some significant advantages over conventional delay lines: they are more compact in size, they still exhibit a linear phase response around the design frequency, they are significantly more broadband, and they can incur a phase lead or lag as well as a 0° phase. The phase shifters are well suited for broadband applications requiring small, versatile, linear phase shifters.
