MODERN TECHNIQUES IN CONVERTER SYSTEMS CARRIER SUPPLY GENERATORS FOR SATELLITE Gerhard COMMUNICATION Heina* ABSTRACT General design considerations for a carrier supply providing a two stage converter for satellite communication systems are discussed. A simple solution by means of a new crystal type and high speed digital dividers is described. The performances of IF and RF local oscillato

A 140 GHz BALANCED MIXER FOR FJNLINE INTEGRATED CmCUITS Wolfgang Menzel * ABSTRAGr First results of a 140 GHz finline balanced mixer are reported. 'Ihe mixer is based on the canbination of finline and coplanar line. Schottky-barrier beam-lead diodes are used as mixer diodes. 'Ihis mixer, together with other finline components under developnent, gives the basis for low-cost 140 GHz integrated fi

A NOVEL DISTRIBUTED MILLIMETER-WAVE Itoh* ISOLATOR Sang Won Yun and Tatsuo ABSTRACT A new distributed millimeter-wave isolator is proposed. The analysis is based on the transverse resonance and the mode matching technique. We obtained a good agreement between the theoretical and the experimental results.
