This is the definitive guide to X-parameters, written by the original inventors and developers of this powerful new paradigm for nonlinear RF and microwave components and systems. Learn how to use X-parameters to overcome intricate problems in nonlinear RF and microwave engineering. The general theory behind X-parameters is carefully and intuitively introduced, and then simplified down to specific, practical cases, providing you with useful approximations that will greatly reduce the complexity of measuring, modeling and designing for nonlinear regimes of operation. Containing real-world case studies, definitions of standard symbols and notation, detailed derivations within the appendices, and exercises with solutions, this is the definitive stand-alone reference for researchers, engineers, scientists and students looking to remain on the cutting-edge of RF and microwave engineering.

A practical, tutorial guide to the nonlinear methods and techniques needed to design real-world microwave circuits.

Covers theoretical and practical aspects related to the behavioral modelling and predistortion of wireless transmitters and power amplifiers. It includes simulation software that enables the users to apply the theory presented in the book. In the first section, the reader is given the general background of nonlinear dynamic systems along with their behavioral modelling from all its aspects. In the second part, a comprehensive compilation of behavioral models formulations and structures is provided including memory polynomial based models, box oriented models such as Hammerstein-based and Wiener-based models, and neural networks-based models. The book will be a valuable resource for design engineers, industrial engineers, applications engineers, postgraduate students, and researchers working on power amplifiers modelling, linearization, and design.

This work presents an overview of the various facets of microwave device behavioral modeling technology, from the mathematical formulation to the required laboratory parameter extraction, focusing its attention on one of the less covered aspects: the embedding and de-embedding procedures associated with the behavioral model extraction process. The discussion starts with the revision of some of the most important behavioral modeling tools, explaining the three most important types of behavioral model formats (polynomial, artificial neural networks, and table-based models) and their instantiation in the context of microwave transistors. Then, it will evolve to the behavioral model parameter extraction procedures, reviewing the required specific microwave instrumentation and correspondent calibration and de-embedding of measurement data. Finally, this chapter will illustrate the use of embedding and de-embedding procedures in the behavioral modeling context, giving a particular emphasis on the needed behavioral model inversion techniques.

Wireless voice and data communications have made great improvements, with connectivity now virtually ubiquitous. Users are demanding essentially perfect transmission and reception of voice and data. The infrastructure that supports this wide connectivity and nearly error-free delivery of information is complex, costly, and continually being improved. This resource describes the mathematical methods and practical implementations of linearization techniques for RF power amplifiers for mobile communications. This includes a review of RF power amplifier design for high efficiency operation. Readers are also provided with mathematical approaches to modeling nonlinear dynamical systems, which can be applied in the context of modeling the PA for identification in a pre-distortion system. This book also describes typical approaches to linearization and digital pre-distortion that are used in practice.
