Progress In Two-Dimensional Horn Imaging Arrays Gabriel Dayalan M. Rebeiz1, Yong GU01, P.A. Stimson1, P. Kasilingam2 and David B. Rutledge1 ABSTRACT Two-dimensional horn-antenna imaging arrays have been fabricated for 93 GHz. In this configuration, a dipole antenna is suspended in a pyramidal horn on a 1-µm silicon oxynitride memb This approach leaves room for low-frequency lines and processing

COMPUTER-CONTROLLED MM- AND SUB-MM WAVE JOSEPHSON SPECTROMETER WITH A PLANAR INTEGRATED FRONT END by J.H. Hinken*, J. Niemeyer**, R. Fromknecht**, M. Klinger*, R. Popel**, W. Richter**, D. Schiel**, U. Stumper**, E. Vollmer*, W. Engelland**, L. Grimm** 1. ABSTRACT MM-wave spectrometers and receivers with wide tuning bandwidths are needed for the analysis of gases as well as for radioastronomy a

ANAL YSIS TRANSISTORS OF TRA VELLING- W AVE INVERTED-GATE FIELD-EFFECT Samir El-Ghazaly* and Tatsuo Itoh* ABSTRACf A unified approach to the analysis the traveling-wave Inverted-Gate FET (INGFET) is presented. The equivalent circuit parameters of the GaAs Inverted-Gate FET, with submicron gate-length, is obtained using a two-dimensional computer model which takes into account the non-stationa

ANALYSIS OF T-JUNCTION IN SQUARE COAXIAL CABLE F. Alessandri and R. Sorrentino" ABSTRACT. A method of analysis of T-junction in square coaxial cable technology is presented. The method is based on a generalization of the transverse resonance method already applied to discontinuities in mm-wave structures using a three dimensional modal expansion technique. 

3-D TLM ANALYSIS Wilf McKenzie, OF E-PLANE TRANSITIONS FOR MM-WAVE NETWORKS Christopher M. Snowden, Michael J. Howes. ABSTRACT The TLM analysis technique is used to obtain the scattering parameters of arbitrarily shaped transitions and discontinuities contained in metallic enclosures. The recently introduced symmetrical condensed TLM node is used with a threedimensional graded mesh scheme

MODELING AND CAD OF AN ULTRA-BROADBAND MONOLITHIC 5-bit DIGITAL ATTENUATOR R. K. Gupta,* J. H. Reynolds,* and P. J. McNally* ABSTRACT The modeling techniques, computer-aided design (CAD) approach, and measured performance of an ultra-broadband (DC-14 GHz) monolithic 5-bit digital attenuator are presented. The two attenuator chips, with total dimensions of 1.3 X 2.7 mm, consume no DC power and pr

APPLICA TION OF CIRCUIT AMPLIFIER SYNTHESIS FOR TO THE DESIGN OF A THREE-STAGE OPTICS RECEIVER 4 MHz to 7 GHz A WIDE BAN D FIBER A. Perennec*, R. Soares**, P. Jarry*, P. Legaud**, R. Boittin** ABSTRACT In fibre optic very high datarate systems it is necessary to have a ultra large band high gain low noise amplifier after the front-end. The purpose of this paper is to show how powerful

SOME RESULTS MEASUREMENT OBTAINED METHOD WITH A NOVEL NEAR-FIELD ANTENNA PATTERN D.E.N. Davies +, A.L. Cullen, E.T. Calazans and H.D. Griffiths * ABSTRACT Far-field radiation patterns of two antennas, obtained from measurements carried out in the near-field region using a novel scattering technique, are presented. The measurement technique and results are described, and some comments o

AN INTEGRATED PLANAR OSCILLATOR LEAKY-WAVE RESONATOR/ANTENNA. J. Birkeland and T. Itoht USING A MICROSTRIP ABS1RACf Recently there has been interest in planar components for quasi-optical systems [1-3]. In such systems the goal is to combine all circuit components with planar antennas. In this paper we describe the design and construction of planar GaAsFET oscillators which use a single leaky-wa
