Abstract (en)

[origin: DE19915246A1] The coupler has carrier substrate and two strip lines. A component is integrated in the secondary coupler loop which causes a phase shift of the frequency of the decoupled signal.

Abstract (de)

Die Erfindung betrifft einen Dünnschichtkoppler mit einem Trägersubstrat (1) und zwei darüberliegenden Streifenleitungen, von denen eine die Hauptkopplerschleife (2) und eine die Nebenkopplerschleife (3) darstellt. Die Verwendung preiswerter Trägersubstratmaterialien und eine kompakte Bauform werden durch Integration einer Streifenleitung, einer Spule oder einer LC-Kombination in die Nebenkopplerschleife (3) ermöglicht. Die Integration dieser Komponenten (4) bewirkt eine Phasenverschiebung der Frequenz des ausgekoppelten Signals und es wird ein Breitbandkoppler erhalten, der bei mindestens zwei Frequenzen dieselbe Kopplung aufweist. <IMAGE>
