MMIC GaAs FOUNDRY IN ISRAEL Dr. ITZCHAK LEWIN EL TA Electronics Industries ISRAEL levin-is.elta.co.il ABSTRACT The increase demand for MMIC based systems in ISRAEL, coupled with the long lead time between specification, design and chip fabrication/realization, led us here in ISRAEL to decide and build a National MMIC Foundry. The Fab which is part of ELTA Electronics Industries, was funded both

INTERCONNECTS AND PACKAGING FOR MMIC'S Wolfgang Menzel Microwave Techniques, University ofUlm, D-89069 Ulm, Germany ABSTRACT This contribution reviews a number of aspects relevant for interconnects and packaging of monolithic integrated millimeter-wave circuits, possibly combined with hybrid or even waveguide circuits. Topics are packaging and front-end architecture, package materials, and sta

Millimeter Wave Fiberoptic Links Peter R. Herczfeld Center for Microwave - Lightwave Engineering Drexel University Philadelphia, PA. 19104, USA Abstract This paper is concerned with the use of fiberoptic links in millimeterwave systems. Two approaches are discussed. The first is an optically fed W-band transceiver. The second describes a mode-lockedmicrochiplaser to be used in optical generation a

OPTICAL SYNTHESIS OF MICROWAVE SIGNALS A. J. Seeds Department of Electronic and Electrical Engineering, University College London, Torrington Place, London, WClE 7JE, England. a.seeds-eleceng.ucl.ac.uk, http://www.ee.ucl.ac. uk ABSTRACT Microwave signals can be generated by the photo-detection of multiple optical signals. This approach has potential for the generation of signals having characteris
