Completely revised and updated to reflect the shifts in this technology from predominantly military applications to the now ubiquitous commercial wireless uses, the second edition of this text contains new chapters or expanded treatment of topics that include software tools for microwave circuit design, two-port networks, RF/microwave systems, lumped and distributed elements, microwave filters, RF switches and attenuators, and BiCMOS and SiGe HBT oscillators. Each chapter concludes with a list of references (referred to in the chapter), bibliography, and group of problems, making this an ideal text for graduate courses in electrical engineering as well as a reference for designers and researchers in the field.
