Written by prominent experts in the field, this authoritative new resource provides guidelines for performing a wide variety of Vector Network Analyzers (VNA) measurements. The capabilities and limitations of modern VNA in the context of challenging real-world applications are explained, as well as insights for optimizing test setups and instrument settings, making accurate measurements and, equally important, avoiding costly mistakes. Organized by topic, the readers can focus on chapters covering particular measurement challenges. Application topics include linear and non-linear measurements of passive and active devices, frequency converting devices, and special considerations for high-power, high-gain, and pulsed devices. Signal Integrity and time-domain reflectometry are covered, as well as emerging applications at millimeter-wave frequencies driven by 5G and automotive radar. Waveguide is presented, with emphasis on understanding guided-wave propagation and the associated calculations required for creating calibration standards. Each application is supported by illustrations that help explain key concepts and VNA screenshots are used to show both expected and, in some cases, unexpected results. This book equips engineers and lab technicians to better understand these important instruments, and effectively use them to develop the technologies that drive our world.

Handbook of Microwave Component Measurements Second Edition is a fully updated, complete reference to this topic, focusing on the modern measurement tools, such as a Vector Network Analyzer (VNA), gathering in one place all the concepts, formulas, and best practices of measurement science. It includes basic concepts in each chapter as well as appendices which provide all the detail needed to understand the science behind microwave measurements. The book offers an insight into the best practices for ascertaining the true nature of the device-under-test (DUT), optimizing the time to setup and measure, and to the greatest extent possible, remove the effects of the measuring equipment from that result. Furthermore, the author writes with a simplicity that is easily accessible to the student or new engineer, yet is thorough enough to provide details of measurement science for even the most advanced applications and researchers. This welcome new edition brings forward the most modern techniques used in industry today, and recognizes that more new techniques have developed since the first edition published in 2012. Whilst still focusing on the VNA, these techniques are also compatible with other vendor's advanced equipment, providing a comprehensive industry reference.

This book provides state-of-the-art coverage for making measurements on RF and Microwave Components, both active and passive. A perfect reference for R&D and Test Engineers, with topics ranging from the best practices for basic measurements, to an in-depth analysis of errors, correction methods, and uncertainty analysis, this book provides everything you need to understand microwave measurements. With primary focus on active and passive measurements using a Vector Network Analyzer, these techniques and analysis are equally applicable to measurements made with Spectrum Analyzers or Noise Figure Analyzers. The early chapters provide a theoretical basis for measurements complete with extensive definitions and descriptions of component characteristics and measurement parameters. The latter chapters give detailed examples for cases of cable, connector and filter measurements; low noise, high-gain and high power amplifier measurements, a wide range of mixer and frequency converter measurements, and a full examination of fixturing, de-embedding, balanced measurements and calibration techniques. The chapter on time-domain theory and measurements is the most complete treatment on the subject yet presented, with details of the underlying mathematics and new material on time domain gating. As the inventor of many of the methods presented, and with 30 years as a development engineer on the most modern measurement platforms, the author presents unique insights into the understanding of modern measurement theory. Key Features: Explains the interactions between the device-under-test (DUT) and the measuring equipment by demonstrating the best practices for ascertaining the true nature of the DUT, and optimizing the time to set up and measure Offers a detailed explanation of algorithms and mathematics behind measurements and error correction Provides numerous illustrations (e.g. block-diagrams for circuit connections and measurement setups) and practical examples on real-world devices, which can provide immediate benefit to the reader Written by the principle developer and designer of many of the measurement methods described This book will be an invaluable guide for RF and microwave R&D and test engineers, satellite test engineers, radar engineers, power amplifier designers, LNA designers, and mixer designers.

Substrate Integrated Suspended Line Circuits and Systems provides a systematic overview of the new transmission line - the substrate-integrated suspension line (SISL). It details the fundamentals and classical application examples of the SISL. The basic SISL concept and structure, various passive circuits and active circuits, and front-end sub-systems are systematically introduced. Featuring research on topics such as high-performance RF/microwave/mm-wave circuits and system, this book is ideal for researchers, engineers, scientists, scholars, educators, and students. Since transmission line is a fundamental component of microwave and mm-wave circuits, the properties of a transmission line, such as losses, size, and dispersion, are vital to the performance of the whole system. Suspended line has been proved to be an excellent transmission line, as it has attractive features such as low loss, weak dispersion, high power capacity, and low effective dielectric constant. However, Conventional waveguide suspended line circuits require metal housing to form air cavities which is Substrate Integrated Suspended Line Circuits and Systems essential to the operation of suspended lines circuits. Also, the metal shell should provide mechanical support and shielding, which contribute to large size and heavy weight. Meanwhile, precise mechanical fabrication and assembling are strongly required, which brings difficulties to the design and fabrication of conventional suspended line circuits, and the manufacturing cost of suspended line circuits increases correspondingly. In this book, we will introduce a new platform of high-performance transmission line, i.e. substrate integrated suspended line (SISL). SISL keeps all the merits of the suspended line while overcomes the drawbacks of conventional waveguide suspended line circuits. Moreover, it is self-packaged and highly integrated. The basic SISL concept and structure, various passive circuits and active circuits, and front-end sub-systems will be systematically introduced. Featuring research on topics such as high-performance RF/microwave/mm-wave circuits and system, this book is ideally designed for researchers, engineers, scientists, scholars, educators, and students.

Despite its continuing popularity, the so-called standard circuit model of compound semiconductor field-effect transistors (FETs) and high electron mobility transistors (HEMTs) is shown to have a limitation for nonlinear analysis and design: it is valid only in the static limit. When the voltages and currents are time-varying, as they must be for these devices to have any practical use, the model progressively fails for higher specification circuits. This book shows how to reform the standard model to render it fully compliant with the way FETs and HEMTs actually function, thus rendering it valid dynamically. Proof-of-principle is demonstrated for several practical circuits, including a frequency doubler and amplifiers with demanding performance criteria. Methods for extracting both the reformulated model and the standard model are described, including a scheme for re-constructing from S-parameters the bias-dependent dynamic (or RF) I(V) characteristics along which devices work in real-world applications, and as needed for the design of nonlinear circuits using harmonic-balance and time-domain simulators. The book includes a historical review of how variations on the standard model theme evolved, leading up to one of the most widely used—the Angelov (or Chalmers) model.
