This book focuses on components such as filters, transformers, amplifiers, mixers, and oscillators. Even the phase lock loop chapter (the last in the book) is oriented toward practical circuit design, in contrast to the more systems orientation of most communication texts.

A much-needed, up-to-date guide to the rapidly growing area of RF circuit design, this book walks readers through a whole range of new and improved techniques for the analysis and design of receiver and transmitter circuits, illustrating them through examples from modern-day communications systems. The application of MMIC to RF design is also discussed.

Reflecting the tremendous explosion of interest in this vital area of the evaluation process, this volume recognizes that deciding what to evaluate is a complex negotiation process that involves the methodological predisposition of the evaluator and the client, client needs, the nature of the program, and the constraints surrounding the evaluation.

How to Focus an Evaluation details five models that characterize different methodological approaches: experimental, goal-oriented, decision-focused, user oriented, and responsive approaches. The text provides valuable advice on how and what type of information to collect from a client; how to clarify and prioritize evaluation concerns; and how to formulate a plan that matches evaluation concerns with appropriate data collection procedures within given cost constraints.
