ANALYSIS OF A TUNABLE DOUBLE-ENDED DIELECTRIC-LOADED MICROWAVERESONATOR M.S. Leong, P.S. Kooi and T.S. Yeo ABSTRACT Many applications require the presence of a dielectric inside a microwave resonator. This paper presents an analysis based on the mode matching technique [1] of a dielectric-loaded cavity that has a configuration which is more generalised than that first proposed by Amman and Morr

RIGOROUS COMPUTATION OF THE FREQUENCY DEPENDANT PROPERTIES FILTERS AND COUPLED RESONATORS COMPOSED FROM TRANSVERSE MICROSTRIP DISCONTINUITIES L.-P. Schmidt OF A8STRACT A numerically efficient method is presented, which yields the propasation constants and the field distributions of basic and hisher order modes of shielded microstrip lines. Upon this basic a mode matchins technique is applied in

HIGH POWER OUTPUT MULTIPLEXER FOR TV-BROADCASTING SATELLITES D. Rosowsky, G. Muller and D. Wolk ABSTRACT The development of a 12 GHz five channel high power output multiplexer for TV-broadcast satellites is described. The maximum input power per channel is 450 W. A manifold type multiplexer made of invar was found to be the best solution. The physical layout is such that the heat generated



A GTD ANALYSIS OF DISCONTINUITIES IN RECTANGULARWAVEGUIDES. V.Daniele , I.Montrosset and R.Zich ABSTRACT: The problem of the junction_between two rectangular waveguides is examined.by ray methods. Results are presented taking into account only a first order approximation (singly diffracted rays) . 



THE TRAVELING WAVE POWER DIVIDER/COMBINER A.G. BERT, D. KAMINSKY * SUMMARY - A new kind of distributed power divider/combiner circuit for use in octave bandwidth (or more) microstrip power transistor amplifier is presented. The design, characteristics tal results on a 4-way divider and advantages are discussed. Experimenare presented and compared with theory.
