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 presents methods for the design of the main microwave active devices. The first chapter focuses on amplifiers working in the linear mode. The authors present the problems surrounding narrowband and wideband impedance matching, stability, polarization and the noise factor, as well as specific topologies such as the distributed amplifier and the differential amplifier. Chapter 2 concerns the power amplifier operation. Specific aspects on efficiency, impedance matching and class of operation are presented, as well as the main methods of linearization and efficiency improvement. Frequency transposition is the subject of Chapter 3. The author presents the operating principle as well as the different topologies using transistors and diodes. Chapter 4 is dedicated to the operation of fixed frequency and tunable oscillators such as the voltage controlled oscillator (VCO) and the yttrium iron garnet (YIG). The final chapter presents the main control functions, i.e. attenuators, phase shifters and switches.

With implications that go to the core of what it means to be human, the issues raised by genetic manipulation-especially cloning-have sparked a passionate debate among governmental, religious, and scientific quarters, as well as the media and the general public. Keeping to the actual science rather than speculation is of the utmost importance for an enlightened approach to this weighty discussion. In clear, lively prose, The Science and Ethics of Engineering the Human Germ Line: Mendel's Maze provides an authoritative treatment of the principles of science and bioethics that bear upon such technologies as germ-line insertion and cloning. It offers a realistic assessment of possible applications, limitations, and new developments likely to arise in these areas. Written by a top physician-investigator, this book progresses from the basics of building a living organism from inanimate parts through to recombinant DNA technology, assisted reproductive technologies, and gene transfer and germ-line engineering. Ethical considerations are woven into this material throughout, while a special section covers the intellectual role played by various social biases. As genetic and reproductive technologies spread from the laboratory to the clinic-and society takes further notice-students and practitioners of biology and medicine, as well as the interested general reader, will find The Science and Ethics of Engineering the Human Germ Line: Mendel's Maze to be an essential and accessible guide to these important subjects.
