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.

Design of Digital Phase Shifters for Multipurpose Communication Systems aims to cover a new emerging need in designing digital phase shifters for modern communication systems. With the advancement of new generation mobile communication systems, directed beams save a substantial amount of RF-power, and improve the noise immunity. In this regard, beam-forming circuits, namely, digital phase shifters constitute essential parts the antenna arrays. Therefore, this book is devoted to design of digital phase shifters for various communications systems. In the good old days, phase shifter design requirements used to demand narrow bandwidth with no physical size constraints. Nowadays, they must be compact and suitable for Very Large Scale Integrated Circuits (VLSI) or Microwave Monolithic Integrated Circuit (MMIC) implementation with Wide Phase Range (WPR) and Wide Frequency Band (WFB). Since the 1980s, the author has been designing digital phase shifters for various applications. He started to work with loaded lines phase shifters, and then employed branch line couplers to achieve wider frequency bands. In order to reduce the physical size, he used a 3 element Symmetric LC ladder based T or PI configurations. In order to achieve broad frequency band with large phase range, usage of LC lattice structures is inevitable. Lately, the author designed phase shifters using both lowpass and highpass LC ladder and lattice based switched-structures, which are suitable for monolithic implementation. In the course of design, MOS transistors were employed as switching elements. This book includes several novel digital phase shifter topologies, which provides wide phase range and wideband operation. Technical topics discussed in the book include:- Basic Concept of Antenna Arrays- Concept of Digital Phase Bit- Scattering Parameters to analyze the electric performance of phase shifters- Transmission Lines as circuit elements to construct practical phase shifters- Loaded Line Digital Phase Shifters (DPS)- Lowpass Based T/PI Section DPS- Highpass Based T/PI Section DPS- 3-Element LC T/PI Section DPS- Wide Phase Range, Wide Frequency Band Symmetric Lattice Based DPS For each topology presented, explicit design equations are provided and programs to assess the electric performance of each topology is developed in a MatLab environment. It is expected that the reader will be self-sufficient to design and implement the digital phase shifters topologies presented in this book.

With MIMO (Multi-Input Multi-Output) based communication technologies advancing since thebeginning of this decade like WiMax and LTE, phased arrays using multi antennas, have becomea hot topic of research. Such phased arrays are composed of phase shifters which enable thebeam to be steered in the direction of maximum energy. This thesis focuses on the design of sucha phase shifter to work in the X band frequencies of the electromagnetic spectrum. The main useof X band has been in the field of Radar, terrestrial communications as well as forcommunications in space. An Analog phase shifter, based upon I/Q Vector Modulation is first designed using idealcomponents in Agilent ADS. The ideal components which provide a perfect response for thephase shifter are replaced using practical components which affect the output of the phaseshifter. The final design gives an insertion loss in the order of 8 dB and also an error in phasethat is around +/-5 degrees. A possible application for the phase shifter that is designed namely in a receiver with phasedarray antennas is also discussed. This super-heterodyne receiver as a complete system can beintegrated together with the phased array and using a suitable algorithm can focus the main lobeof the phased array antenna in the direction that is desired. Once the system is integrated, it canbe put to practical usage.
