The 4th edition of this classic text provides a thoroughcoverage of RF and microwave engineering concepts, starting fromfundamental principles of electrical engineering, with applicationsto microwave circuits and devices of practical importance. Coverage includes microwave network analysis, impedance matching,directional couplers and hybrids, microwave filters, ferritedevices, noise, nonlinear effects, and the design of microwaveoscillators, amplifiers, and mixers. Material on microwave and RFsystems includes wireless communications, radar, radiometry, andradiation hazards. A large number of examples and end-of-chapterproblems test the reader's understanding of the material. The 4thedition includes new and updated material on systems, noise, activedevices and circuits, power waves, transients, RF CMOS circuits,and more.
