Directions for the Next Generation of MMIC Devices and Systems

Microwave and millimeter-wave integrated circuits (MMICs) are of increasing im- portance in modern military and commercial wireless communication systems. Current trends are towards low-cost high-density multilevel and multifunctional integration cover- ingmillimeterand submillimeterwave regions.The integrationofdiverse subfunctions such as light-wave devices superconductor circuits digital circuits and ferrite devices together with conventional microwave or millimeter-wave devices circuits and antennas will allow implementation of large systems on a single chip. Research on advanced device concepts 3-D interconnects high-performance packaging methods advanced CAD-tools measure- ment and testing techniques as weil as material and fabrication technologies are being di- rected to meet these new challenges. Continuing on the series ofsymposia sponsored by the Weber Research Institute of Polytechnic University an international symposium focusing on the current developments and new research initiatives for the next generation ofmicrowave and millimeter wave inte- grated circuits and systems was held at Brooklyn New York during September 11-13 1996. The symposium was organizedas a3-dayevent running mostly ina single-session format of regular papers and panel discussions It was co-sponsored by the Army Research Office Re- search Triangle Park NC in cooperation with the IEEE Microwave Theory and Techniques Society the IEEE Antennas and Propagation Society and IEEE Long Island and New York MetropolitanSections.The papers published in this volume are extended versionsofselected papers presented at this symposium.
