Summary

This straightforward volume takes a distributed, transmission line approach to RF circuit design, with a focus on methodology fundamentals and minimal discussion of theoretical concepts. The Second Edition introduces RF design tools such as the Smith Chart, dual port networks, S-parameters, and provides extensive coverage of RF filter design, matching networks, active and passive device modeling, narrow and broadband amplifiers, mixers, and oscillators. Approaches RF design from a circuit perspective, so readers need little or no background in electromagnetic fields. Prominently features key RF concepts in sidebars throughout the text. Provides hands-on experience via accompanying MATLAB CD. For anyone interested in learning more about RF circuit design.
