ANTENNA METERS PHASE PATTERN MEASUREMENTS USING THREE POWER Arto Lehto, J ussi Tuovinen, Olga Boric, Antti Raisanen ABSTRACT A phaseless antenna phase pattern measurement method has been demonstrated at millimeter waves using three power meters instead of a phase sensitive measurement device. The conventional phase measurement device is replaced by three power dividers and three power mete

REAL TIME ANALY6~R . OF ANTENNA . NEAR-FIELD DISTRIBUTION 1 D.Plcar d 1 ,J. Ch .Bo 1omey 1 , A.Zlyyat ABSTRACT This paper describes a new facility for rapid near-field measurement in cylindrical coordinates. This facility is hardware and software optimized and allows quasi-real time measurements on large antennas in a frequency range extending from 2 to 10 GHz. By comparison to classica

A NEW TYPE J. Tuovinenx., ABSTRACT OF COMPACT ANTENNA TEST RANGE A. Vasara+ and A. Raisanenx The application of conventional reflector type compact antenna test ranges (CATR), becomes increasingly difficult above 100 GHz. The main problems are the tight surface accuracy requirements for the reflector, and therefore the high manufacturing costs. These problems can be overcome by the use of a n

THS HIGH-POWER O-TY1?E Mivi-WAVE OSCILLATORS FOR PROCESS APPLICATIONS B.A. Belyavsky-, ABSTRACT G.I.Goryacheva-, M.I.Lapin-, L.V.Maletsky- The expediency of application of resonant TWTs in the processing devices of mm-wave range is considered. The basic design of the permanent magnet-packaged oscillator havingCW-power of 1.5 kW at 34 GHz has been developed. Lately there has been observed an in

Design of Series Feedback Millimeter Wave Oscillators employing Whispering Gallery Mode Dielectric Resonators Walter Gross, Franz-Josef Abstract Design and performance of millimeter wave oscillators at 36.5 GHz and 44.5 GHz employing Whispering Gallery Mode Dielectric Resonators (WGMDR) and commercially available HEMTs are presented. A special microstrip coupling circuit has been developed for the

17.6% Conversion Efficiency At 60 GHz with IMP ATT Diodes ? "1 J.-F. Luy1, F.Schaffler , M.Schlett 2 Abstra.ct For the use in mobile systems high efficiency V-band IMP ATT diodes for CW operation are developed. The design is based on a numerical large signal drift diffusion model. Flat-profile and low-high-low structures are simulated and the layers are grown by silicon molecular beam epitaxy. So

A CW GAAs TUNNETT DIODE SOURCE FOR 100 GHz AND ABOVE H. Eisele, C. Kidner, G. I. Haddad ABSTRACf GaAs p++n+nn+ TUNNELL diodes have been designed for operation around 100 GHz using a saturated drift velocity of 4.6 x 106 cms-l for electrons at high electric fields and a temperature of 500 K. Diodes on integral heat sinks have been successfully fabricated and tested in this frequency range in a W

BROADBAND FILTER CIRCUITS USING AN EXTENDED SUSPENDED SUBSTRATE TRANSMISSION LINE CONFIGURATION Wolfgang Menzel ABSTRACT Suspended stripline has proven to be a low loss transmission line, especially for filters. Making full use of both sides of the substrate, including standard stripline, coupled stripline and microstrip, very broadband components can be realized. This is demonstrated by a 2.5 GHz
