CONTENIDO:

This book provides a thorough, practical introduction to the theory and design of microwave amplifiers and oscillators. It explains the technical terms and examines the concepts behind the design of optimum-performance amplifiers and oscillators. The first part of the book is a basicintroduction to the scattering matrix. It considers the concepts of current, voltage and impedance; the basic properties of the scattering matrix, and the precautions necessary when using it at high frequencies. The second section is devoted to the two-port amplifier, defining matching, stability and gain. Three basic examples of amplifier design involving the application of microstrip technology are then provided in part 3, which also introduces a new approach to generalization of the critical instability circle concept for use in designing maximum instability oscillators. In the final section, S parameters and noise measurement are considered, with particular attention given to the network analyser and methods of noise evaluation for assessing the performance of amplifiers.
