A DIGITAL MICROWAVE NETWORK ANALYZER *) Klaus Matkey and Hans-Jiirgen ABSTRACT Meckelburg **) A new method for amplitude and phase measurements of time harmonic microwave signals is presented. By means of a harmonic mixer the HF signal is mixed down to an IF frequency, sampled and then processed digitally in a minicomputer. As the IF signal is processed digitally it is not necessary that the

GaAs MONOLITHIC ASTABLE MULTIVIBRATOR TYPE VCO OPERABLE UP TO KU BAND Masafumi Shigaki, Kenichi Imamura, Yoshimasa Daido ABSTRACT The estimated theoretical limit to oscillation frequency predicts that the frequency of a GaAs monolithic astable multiviblator type oscillator can be increased from the maximum reported frequency of 5 GHz to 17 GHz by optimization of circuit parameters. The increas

HIGH REAL ESTATE EFFICIENCY, WIDEBAND MONOLITHIC GaAs AMPLIFIERS* . Vlad PAUKER, Bernard BRU, Michel BINET Abstract Small size wideband MMIC amplifiers of two types: high gain and low noise have been developed. DC coupling through the buffer stages have been used to avoid the MIM capacitors which take room and need a more complex technology. A real estate efficiency of 110 dB/mm2 has been

OPTIMOH DESIGN OF DUAL GATE MESFET AMPLITUDE MODULATORS Roman MEIERER and Christos TSIRONIS Abstract Ku band variable gain-constant phase amplifiers have been developed using dual gate FETs and appropriate CAD techniques. Obtained performances of the realized MIC at 15 GHz are: gain control of 26 dB associated with phase modulation of about 10 degrees and a maximum transmission gain of 4 dB in

SUPERCONDUCTINGMMICswith 1474 JOSEPHSON JUNCTIONS PROVIDING STANDARD VOLTAGES up to 1.2 VOLT Johann H. Hinken+s JUrgen Niemeyer+s Richard L. Kautz++ ABSTRACT High precision dc voltage standards utilize microwave induced constant voltage steps occurring due to the ac Josephson effect. Existing standards can be considerably simplified and improved by using a large number of series-connected Jos

A MONOLITHIC 800 MHz BANDWIDTH DBS FRONT-END RECEIVER FOR MASS PRODUCTION. E.M. BASTIDA*, E. CAVALIERI G. FAZZINI**, G. SIMONETTI** D'ORO**, G.P. DONZELLI***, N. FANELLI * , ABSTRACT The paper describes the activity directed towards the production of a monolithic DBS front-end receiver. The basic technological choises for the front-end production are discussed. Main design features a

THE FIRST GaAs FULLY INTEGRATED MICROWAVE RECEIVER FOR DBS APLlCATIONS AT 12 GHz Christian KERMARREC,Jacques FAGUET, Bertrand VANCON Claude MAYOUSSE, Andr~ COLLET, pierre KAIKATI, Dominique BEAUFORT Abstract Individual monolithic chips fulfilling each function of a 12 GHz DBS receiver have been already demonstrated by LEP (1) and other laboratories (2) (3) (4). For the first time, a fully integr



INTRODUCTION TO THE COMPUTER AIDED DESIGN OF MICROWAVE CIRCUITS. G.R. Hoffman - University of Gent, Belgium ABSTRACT In this tutorial paper, a general introduction is given to the topic of designing microwave circuits by digital computer. Common aspects in CAD of other electronic circuits, and indeed many other systems are discussed, while problems and possibilities that are typical for
