Abstract

Abstract Translated from German 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. <IMAGE> The invention relates to a directional coupler that can be produced entirely in integrated technology (MIC or MMIC), in particular for the X-band. The directional coupler can preferably be designed for high coupling attenuation (> 30 dB) and high directional sharpness (> 30 dB) with a large relative bandwidth (approximately 20%). This is achieved by a step-like arrangement of several λ / 4 waveguides and coupling capacitors arranged between the paths of the coupler. <IMAGE>
