NEW TECHNOLOGIES IN PHASED ARRAY RADAR E R BILLAM * ABSTRACT The current situation in phased array radar is reviewed and the implications of the considerable advances in the technology relevant to phased array radar in the last decade, in particular developments in monolithic microwave integrated circuits, are considered. 

RECENT DEVELOPMENTS AND TRENDS IN OPTICAL COMMUNICATION H.-G. Unger* ABSTRACT Recent Developments in optical communication such as dynamic-single-mode lasers, low-loss single-mode fibers of low dispersion and sensitive InGaAsP-avalanche photodiodes with fast response lead to fiber systems with pulse rate regenerator distance products of 25 Gbit km/s per fiber. With wavelength multiplexing mo

TERRESTRIAL INTERFACES J R Forrest MOBILE COMMUNICATIONS - CELLULAR, SATELLITE AND THEIR ABSTRACT A general description of both cellular and satellite communication systems for mobile terrestrial communications is given. The current state of development and use of these systems is given, together with predictions for expansion of the networks into new markets, such as an extension of the pub



HETEROSTRUCTURE TRANSISTOR TECHNOLOGY A NEW FRONTIER IN MICROWAVE Charles A. Liechti* - ELECTRONICS ABSTRACT Two transistors are taking over the lead in the race for highest speed: the High-Electron Mobility Transistor (HEMT) and the Heterojunction Bipolar Transistor (HBT). Both devices exploit unique aspects of electron transport at the interface between compound semiconductors of different ba

VANISHING FRONTIER BETWEEN FAR INFRARED AND MICROWAVE: AND GYROTRONS. (AN OVERVIEW). FIR LASERS P. Grivet G. Mouriert ABSTRACT. A lack of coherent and efficient sources subsisted in the submillimetric domain. Recent work has alleviated this deficiency in a two pronged attack. One action leads to study in depth the laser mechanism based on stimulated emission and optical pumping. Another relies

OPTIMAL DESIGN MULTIPLEXERS OF MULTI-CAVITY FILTERS AND CONTIGUOUS-BAND J.W. Bandler"+, S.H. Chen", S. Daijavad" and W. Kellermann" A general contiguous-band multiplexer optimization procedure exploiting exact network sensitivities is described. The structure under consideration consists of synchronously and asynchronously tuned multi-cavity filters distributed along a waveguide manifold.

Ca.1PlITER AIDED DESIGN OF A NONDISPERSIVE MAGNETOSTATIC WAVE DELAY LINE WITH ELECTRONIC TUNABILITY L.K. Ullrich and R. Horn *) ABSTRACT Nondispersive, electronically tunable delay devices can be constructed by cascading two highly dispersive magnetostatic delay lines with opposite dispersion characteristics. A computer program is described that simulates such a series connection and comput

COMPUTER MODELS FOR MMIC CAPACITORS AND INDUCTORS Ingo Wolff and Godfrey Kibuuka Abstract Computer models for MMIC interdigitated capacitors and rectangular spiral inductors are described. The theory of the interdigitated capacitor considers the influence of the metallization thickness, the end effects of the fingers, the exact position of the fingers on the main line and of the T-junctions
