Book Description
Treats oscillators as the sum of two circuit elements: the active circuit element (including the transistor) and the frequency-determining resonant circuit element. This book provides step-by-step procedures for designing each element in isolation and then combining them to produce the oscillator.

Book Description
Delivering the best possible solution for phase noise and outputpower efficiency in oscillators This complete and thorough analysis of microwave oscillatorsinvestigates all aspects of design, with particular emphasis onoperating conditions, choice of resonators and transistors, phasenoise, and output power. It covers both bipolar transistors andFETs. Following the authors' guidance, readers learn how to designmicrowave oscillators and VCOs that can be tuned over a very widefrequency range, yet have good phase noise, are low cost, and aresmall in size. All the essential topics in oscillator design anddevelopment are covered, including: * Device and resonator technology * Study of noise sources * Analysis methods * Design, calculation, and optimization methodologies * Practical design of single and coupled oscillators While most of the current literature in the field concentrates onclassic design strategies based on measurements, simulation, andoptimization of output power and phase noise, this text offers aunique approach that focuses on the complete understanding of thedesign process. The material demonstrates important design rulesstarting with the selection of best oscillator topology, choice oftransistors, and complete phase noise analysis that leads tooptimum performance of all relevant oscillator features. Alsoincluded are CMOS oscillators, which recently have become importantin cellular applications. For readers interested in specializedapplications and topics, a full chapter provides all the necessaryreferences. The contents of the text fall into two major categories: * Chapters 1 through 9 deal with a very detailed and expandedsingle resonator oscillator, including a thorough treatment of bothnonlinear analysis and phase noise * Chapters 10 and 11 use the knowledge obtained and apply it tomultiple coupled oscillators (synchronized oscillators) This text is partially based on research sponsored by the DefenseAdvanced Research Projects Agency (DARPA) and the United StatesArmy and conducted by Synergy Microwave Corporation. With thewealth of information provided for the analysis and practicaldesign of single and synchronized low-noise microwave oscillators,it is recommended reading for all RF microwave engineers. Inaddition, the text's comprehensive, step-by-step approach makes itan excellent graduate-level textbook.

Book Description
The new edition of the leading resource on designing digital frequency synthesizers from microwave and wireless applications, fully updated to reflect the most modern integrated circuits and semiconductors Microwave and Wireless Synthesizers: Theory and Design, Second Edition, remains the standard text on the subject by providing complete and up-to-date coverage of both practical and theoretical aspects of modern frequency synthesizers and their components. Featuring contributions from leading experts in the field, this classic volume describes loop fundamentals, noise and spurious responses, special loops, loop components, multiloop synthesizers, and more. Practical synthesizer examples illustrate the design of a high-performance hybrid synthesizer and performance measurement techniques—offering readers clear instruction on the various design steps and design rules. The second edition includes extensively revised content throughout, including a modern approach to dealing with the noise and spurious response of loops and updated material on digital signal processing and architectures. Reflecting today's technology, new practical and validated examples cover a combination of analog and digital synthesizers and hybrid systems. Enhanced and expanded chapters discuss implementations of direct digital synthesis (DDS) architectures, the voltage-controlled oscillator (VCO), crystal and other high-Q based oscillators, arbitrary waveform generation, vector signal generation, and other current tools and techniques. Now requiring no additional literature to be useful, this comprehensive, one-stop resource: Provides a fully reviewed, updated, and enhanced presentation of microwave and wireless synthesizers Presents a clear mathematical method for designing oscillators for best noise performance at both RF and microwave frequencies Contains new illustrations, figures, diagrams, and examples Includes extensive appendices to aid in calculating phase noise in free-running oscillators, designing VHF and UHF oscillators with CAD software, using state-of-the-art synthesizer chips, and generating millimeter wave frequencies using the delay line principle Containing numerous designs of proven circuits and more than 500 relevant citations from scientific journal and papers, Microwave and Wireless Synthesizers: Theory and Design, Second Edition, is a must-have reference for engineers working in the field of radio communication, and the perfect textbook for advanced electrical engineering students.

Book Description
Use of high overtone bulk acoustic resonators (HBAR) has made possible development of low phase noise multiple frequency microwave sources operating directly at microwave frequencies. Most recently a low noise source has been developed at L-band which provides signals at approximately 5-MHz intervals and achieves phase noise suppression equivalent to sources based on low frequency quartz crystal stabilization and multiplication. The direct microwave HBAR multiple frequency source requires a fraction of the hardware required to achieve the same phase noise suppression for multiple microwave frequency operation by any other means.

Book Description
This practically-oriented, all-inclusive guide covers all the major enabling techniques for current and next-generation cellular communications and wireless networking systems. Technologies covered include CDMA, OFDM, UWB, turbo and LDPC coding, smart antennas, wireless ad hoc and sensor networks, MIMO, and cognitive radios, providing readers with everything they need to master wireless systems design in a single volume. Uniquely, a detailed introduction to the properties, design, and selection of RF subsystems and antennas is provided, giving readers a clear overview of the whole wireless system. It is also the first textbook to include a complete introduction to speech coders and video coders used in wireless systems. Richly illustrated with over 400 figures, and with a unique emphasis on practical and state-of-the-art techniques in system design, rather than on the mathematical foundations, this book is ideal for graduate students and researchers in wireless communications, as well as for wireless and telecom engineers.
