As part of a satellite communications network, VSATs allow earth terminals to be located on users' premises to provide data or voice and video services; they can be established rapidly and reconfigured to respond to changing communications needs flexibly and cost effectively. Twenty-eight contributions describe the key technology underlying these systems, representative systems from various vendors, budgets, protocols, service provision, economic, and regulatory issues. For those involved in telecommunications systems management or the engineering aspects. Annotation copyright by Book News, Inc., Portland, OR

This peer-reviewed book explores the methodologies that are used for effective research, design and innovation in the vast field of millimeter-wave circuits, and describes how these have to be modified to fit the uniqueness of high-frequency nanoelectronics design. Each chapter focuses on a specific research challenge related to either small form factors or higher operating frequencies. The book first examines nanodevice scaling and the emerging electronic design automation tools that can be used in millimeter-wave research, as well as the singular challenges of combining deep-submicron and millimeter-wave design. It also demonstrates the importance of considering, in the millimeter-wave context, system-level design leading to differing packaging options. Further, it presents integrated circuit design methodologies for all major transceiver blocks typically employed at millimeter-wave frequencies, as these methodologies are normally fundamentally different from the traditional design methodologies used in analogue and lower-frequency electronics. Lastly, the book discusses the methodologies of millimeter-wave research and design for extreme or harsh environments, rebooting electronics, the additional opportunities for terahertz research, and the main differences between the approaches taken in millimeter-wave research and terahertz research.

This volume reviews approaches to and topologies of Ku-band transmitters. It explores the advantages and disadvantages of these transmitters along with critical design criteria necessary to enhance system performance. Readers will learn to analyze, design and characterize transceiver modules.

Broadband RF and Microwave Amplifiers provides extensive coverage of broadband radio frequency (RF) and microwave power amplifier design, including well-known historical and recent novel schematic configurations, theoretical approaches, circuit simulation results, and practical implementation strategies. The text begins by introducing two-port networks to illustrate the behavior of linear and nonlinear circuits, explaining the basic principles of power amplifier design, and discussing impedance matching and broadband power amplifier design using lumped and distributed parameters. The book then: Shows how dissipative or lossy gain-compensation-matching circuits can offer an important trade-off between power gain, reflection coefficient, and operating frequency bandwidth Describes the design of broadband RF and microwave amplifiers using real frequency techniques (RFTs), supplying numerous examples based on the MATLAB® programming process Examines Class-E power amplifiers, Doherty amplifiers, low-noise amplifiers, microwave gallium arsenide field-effect transistor (GaAs FET)-distributed amplifiers, and complementary metal-oxide semiconductor (CMOS) amplifiers for ultra-wideband (UWB) applications Broadband RF and Microwave Amplifiers combines theoretical analysis with practical design to create a solid foundation for innovative ideas and circuit design techniques.

This book is the first standalone book that combines research into low-noise amplifiers (LNAs) with research into millimeter-wave circuits. In compiling this book, the authors have set two research objectives. The first is to bring together the research context behind millimeter-wave circuit operation and the theory of low-noise amplification. The second is to present new research in this multi-disciplinary field by dividing the common LNA configurations and typical specifications into subsystems, which are then optimized separately to suggest improvements in the current state-of-the-art designs. To achieve the second research objective, the state-of-the-art LNA configurations are discussed and the weaknesses of state-of the art configurations are considered, thus identifying research gaps. Such research gaps, among others, point towards optimization – at a systems and microelectronics level. Optimization topics include the influence of short wavelength, layout and crosstalk on LNA performance. Advanced fabrication technologies used to decrease the parasitics of passive and active devices are also explored, together with packaging technologies such as silicon-on-chip and silicon-on-package, which are proposed as alternatives to traditional IC implementation. This research outcome builds through innovation. Innovative ideas for LNA construction are explored, and alternative design methodologies are deployed, including LNA/antenna co-design or utilization of the electronic design automation in the research flow. The book also offers the authors’ proposal for streamlined automated LNA design flow, which focuses on LNA as a collection of highly optimized subsystems.
