Book Description
Design and construction of a prototype X-band pulse-Doppler radar having 90 dB of dynamic range (after pulse integration and into a 1 MHz band) calls for a ultra-low phase noise multi-frequency source. The generated frequencies for local oscillators (LOs), waveform generation, and data acquisition typically cover the spectrum from HF to X-band and must be coherent. However, using a separate synthesizer for each required frequency would be both costly and cumbersome. This report describes an inexpensive, lightweight, compact, low phase-noise source that coherently generates, within a single chassis, all the frequencies required of a high-performance radar system. Moreover, the multi-frequency source has a tunable output providing frequencies from UHF to K-band. This report emphasizes "how to build" rather than detailed design theory. However, the report does present phase-noise test results and suggested improvements for a second design iteration. The multi-frequency source is versatile and can also be used for bench testing RF and microwave components.

Book Description
This book contains a thorough treatment of phase noise, its relationship to thermal noise and associated subjects such as frequency stability. The design of low phase noise signal sources, including oscillators and synthesisers, is explained and in many cases the measured phase noise characteristics are compared with the theoretical predictions. Full theoretical treatments are combined with physical explanations, helpful comments, examples of manufactured equipment and practical tips. Overall system performance degradations due to unwanted phase noise are fully analysed for radar systems and for both analogue and digital communications systems. Specifications for the acceptable phase noise performance of signal sources to be used in such systems are derived after allowing for both technical and economic optimisation. The mature engineer whose mathematics may be somewhat rusty will find that every effort has been made to use the lowest level of mathematical sophistication that is compatible with a full analysis and every line of each mathematical argument has been set out so that the book may be read and understood even in an armchair. Due to a novel approach to the analytical treatment of narrow band noise, the book is simple to understand while simultaneously carrying the analysis further in several areas than any existing publication.

Book Description
This book introduces low-noise and low-power design techniques for phase-locked loops and their building blocks. It summarizes the noise reduction techniques for fractional-N PLL design and introduces a novel capacitive-quadrature coupling technique for multi-phase signal generation. The capacitive-coupling technique has been validated through silicon implementation and can provide low phase-noise and accurate I-Q phase matching, with low power consumption from a super low supply voltage. Readers will be enabled to pick one of the most suitable QVCO circuit structures for their own designs, without additional effort to look for the optimal circuit structure and device parameters.

Book Description
Active remote sensing is the principal tool used to study and to predict short- and long-term changes in the environment of Earth - the atmosphere, the oceans and the land surfaces - as well as the near space environment of Earth. All of these measurements are essential to understanding terrestrial weather, climate change, space weather hazards, and threats from asteroids. Active remote sensing measurements are of inestimable benefit to society, as we pursue the development of a technological civilization that is economically viable, and seek to maintain the quality of our life. A Strategy for Active Remote Sensing Amid Increased Demand for Spectrum describes the threats, both current and future, to the effective use of the electromagnetic spectrum required for active remote sensing. This report offers specific recommendations for protecting and making effective use of the spectrum required for active remote sensing.

Book Description
This book, now in its fourth edition, is a well-known classic on the ultrafast nonlinear and linear processes responsible for supercontinuum generation. The book begins with chapters reviewing the experimental and theoretical understanding of the field along with key applications developed since the discovery of the supercontinuum effect. The chapters that follow cover recent research activity on supercontinuum phenomena, novel applications, and advances achieved since the publication of the previous edition. The new chapters focus on: filamentation in gases, air, and condensed media; conical emission by four-wave mixing and X-waves; electronic self-phase mechanism; higher harmonics generation; attosecond laser pulses; complex vector beam supercontinuum; higher order self-phase modulation and cross-phase modulation; nonlinear supercontinuum interference in uniaxial crystals; new nonlinear microscopes involving supercontinuum and ultrafast lasers with biomedical applications; and other current supercontinuum applications in communications. The Supercontinuum Laser Source is a definitive work by one of the discoverers of the white light effect. It is indispensable reading for any researcher or student working in the field of ultrafast laser physics.

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.
