Abstract

Die Erfindung betrifft einen Richtkoppler, der vollständig in integrierter Technologie (MIC oder MMIC) herstellbar ist, insbesondere für das X-Band. Der Richtkoppler kann vorzugsweise für eine hohe Koppeldämpfung (>30 dB) und eine hohe Richtschärfe (>30 dB) ausgelegt werden bei einer großen relativen Bandbreite (ungefähr 20%). Dieses wird erreicht durch eine stufenförmige Anordnung aus mehreren λ/4-Wellenleitern und zwischen den Pfaden des Kopplers angeordneten Koppelkondensatoren.
