RFIC and MMIC technology provides the core components for many microwave and millimetre-wave communications, radar and sensing systems. Recent years have seen exciting developments, such as circuits operating to over 200 GHz, millimetre-wave micromachined antenna arrays and microelectromechanical systems (MEMS). At the same time, the rapid growth of wireless communications in the 1 to 6 GHz range has seen a dramatic shift towards advanced silicon technology. It is timely, therefore, to introduce this fully up-to-date second edition of a world-renowned standard text. With over 1000 references and 350 figures, the book gives an in-depth account of GaAs, InP, Si and SiGe technologies and describes all the key techniques for the design of amplifiers, oscillators, mixers, switches, variable attenuators, phase shifters, integrated antennas and complete monolithic transceivers. It is essential reading as both a tutorial guide for those new to RFIC and MMIC design and as a circuit design handbook for experienced engineers.
