This paper presents coplanar millimeter-wave monolithic integrated circuits with high performance and small size for use in low noise communication and radar system applications. Technology and modeling issues with respect to active and passive elements are discussed first. In a second step, the potential of coplanar waveguides to realize compact ICs is illustrated through various design examples, such as low noise amplifiers, mixers and power amplifiers. The performance of multifunctional ICs is also presented by comparing simulated and measured results for a complete 77 GHz Transceive MMIC.

For sensor and communication system applications, monolithic microwave integrated circuits (MMICs) feature performance, functionality, reliability, and competitive price. In this paper, the potential of PHEMT ICs for communication and sensor applications up to 100 GHz is discussed. Specifically, I will address the application of coplanar waveguide technology for rf ICs, millimeter-wave multifunctional ICs and power amplifiers, as well as mixed-signal ICs and OEICs. A 77-GHz transceiver MMIC designed for automotive collision avoidance radar is presented as an example of a very compact, multifunctional mm-wave chip. A chip set for active and passive imaging at 94 GHz includes low noise and high gain amplifiers, low phase noise oscillators, and phase shifters. An FMCW module is conceived for material characterization. A family of coplanar power amplifier MMICs for wireless communication in the range of 20 to 60 GHz with output powers up to 1 W is presented. Finally, integrated circuits for high-speed data transmission at 40 Gbit/s will be discussed. Int. J. Hi. Spe. Ele. Syst. 2000.10:393-411.
