COPLANAR LUMPED ELEMENTS AND THEIR APPLICATION IN FILTERS ON CERAMIC AND GALLIUM ARSENIDE SUBSTRATES Godfrey Kibuuka, Ralf Bertenburg, ABSTRACT: Propagation characteristics (dielectric contants, characteristic impedances and losses) of coplanar waveguides based on full wave spectral domain analysis are presented in this paper. Theoretical results of single coplanar waveguides fabricated on ceramic

Passive Lumped Element Multi-Layer Thin-Film Circuits Bruce Kopp* ABSTRACT The capabilities and advantages of multi-layer thin-film lumped element circuits over distributed and discrete lumped component circuits are discussed. Schematics, photographs, and measured data for a band-pass filter, three-way power divider, and phase shifter are provided to illustrate these advantages. 

WAVEGUIDE RADIAL-RESONATOR WAVE POWER CIRCUIT ANALYSIS SOURCES FOR THE DESIGN OF MILLIMETER N. Haese, P.A. Rolland ABSTRACT A computer-aided design model was developed to analyse millimeter wave rectangular waveguide circuits. Particular attention was paid to cap circuits and Pretuned Modules for Gunn and IMPATT diodes in the W band (75-110 GHz). The theoretical results are verified through

HYBRID MODES, LOSSES AND SUBSTRATE LEAKAGE OF SLOTLINE AT MILLIMETRE WAVE FREQUENCIES , G Corti ** T Rozzi* , F Moglie*, E Marchionna** Abstract Slotline has proved its usefulness higher frequencies as a trasmission media in the lower microwave range. Its use at guided requires, however, proper characterization not only of the fundamental mode, which is now hybrid, but also of it

NEW DESIGN ASPECTS FOR HIGH ACCELERA nON HARDENED MILLIMETERW AVE COMPONENTS Wolfgang ABSTRACT Holpp ... Millimeterwave components and systems for high acceleration applications must be characterized by specific mechanical features, excellent electrical ones being presupposed. Depending on the carrier linear accelerations of up to 20,000 g have to be taken into account. Presently, the most

Direct Synthesis of Waveguide Filters considering Filter Losses unsymmetrical w. Mahler, J. Brettschneider, F. Landstorfer * Abstract Filters which are designed exclusively with regard to their geometrical proportions, i.e. neglecting losses, show an ideal transmission behaviour /1/. In contrast to this, measurements of real filters, owing to losses, indicate not only an increase in passban

A NOVEL WAVEGUIDE QUADRUPLEXER MILLIMETER WAVE APPLICATIONS FOR R. Vahldieck and B. Varailhon de la Filolie Department of Electrical and Computer Engineering University of Victoria P.O. Box 1100 Victoria, B.C. V8W 2Y2 ABSTRACT This paper describes the analysis and design of a novel wave multiplexer. The component is composed of two E-plane and a tapered 6-dB waveguide grid-divider. Rigorous fiel

AN MMIC BPSK MODULATOR FOR SATELLITE COMMUNICATION A R Reddy, R M Mishra and R Chattopadhyaya Abstract An MMIC BPSK modulator is designed and realised using 0.5 micron MESFETs on GaAs wafer. BPSK modulation function is achieved using a novel active phase splitter and DPST switch. The modulator occupies an area of 1 mm square and dissipates 75 mW of power. The measured results indicate a carrier

Gluck ANADIGICS, INC. 35 Technology Drive Warren, New Jersey 07060 ABSTRACT This paper describes a temperature compensated L-band GaAs MMIC successive detection logarithmic amplifier (SDLA) featuring ultra low power consumption. Log-linearity of +2.5dB and a dynamic rang

MINIATURISED BROADBAND DETECTORS USING MiMAC TECHNOLOGY FOR HIGH PERFORMANCE ESM APPLICATIONS R. Aliwell*, S. Neylon* ABSTRACT A range of miniaturized broadband detectors has recently been developed employing monolithic integrated microwave alumina circuits (MiMAC) technology. Germanium tunnel diodes; silicon sChottky detectors and gallium arsenide (GaAs) planar doped barrier (PDB) diodes
