Description
Durch die DE-AS 10 86 307 ist bereits ein Richtungskoppler bekannt, bei dem der als Streifenleiter ausgeführte Koppelleiter wieder in Koaxialleitungstechnik aus der Koppelzone herausgeführt, sodaß er unmittelbar dazu verwendbar ist, eine richtungsabhängige Kopplung zwischen zwei koaxialen Leitungskreisen herzustellen.From DE-AS 10 86 307 a directional coupler is already known in which the designed as a stripline Coupling conductor again led out of the coupling zone using coaxial line technology, so that it is immediately a direction-dependent coupling between two coaxial line circuits can be used for this purpose to manufacture.
Der Erfindung liegt die Aufgabe zugrunde, einen Richtungskoppler aufzuzeigen, der unmittelbar für die richtungsabhängige Kopplung zwischen einem koaxialen Leitungskreis und einem Leitungskreis in unsymmetrischer Streifenlciiungstcchnik verwendbar ist.The invention is based on the object of showing a directional coupler that is directly for the Direction-dependent coupling between a coaxial line circuit and a line circuit in an asymmetrical one Strip removal technique can be used.
Krfindungsgemäß wird dies durch die im llauptanspruch angegebenen Merkmale gelöst.According to the invention, this is made possible by the main claim specified features solved.
Die in den Untersprüchcn angegebenen Merkmalen betreffen besonders zweckmäßige Ausgestallungen der Erfindung.The features specified in the sub-claims relate to particularly expedient configurations of the Invention.
Anhand eines Ausführungsbeispieles sollen die Erfindung und die damit erzielbaren Vorteile im folgenden näher erläutert werden.On the basis of an exemplary embodiment, the invention and the advantages that can be achieved with it are described below are explained in more detail.
In den Fig. la—Ic ist ein gemäß der Erfindung konstruktiertes Ausführungsbeispiel gezeigt, das einen 30 dB Koppler betrifft, der eine 50 Ω-Streifenleitung und eine 50 Ω-Koaxialleitung enthält. Der Innenleiter der Koaxialleitung ist mit 1, der zugehörige Außenleiter mit 2 bezeichnet. Die Streifenleitung wird durch eine in an sich bekannter Weise auf ein Dielektrikum 5 aufgebrachte Metallfolie 3 bebildet. Durch geeignete Wahl der Dimensionierung erhält man eine Richtkopplung zwischen dem koppelnden Teil 3 der erwähnten Streifenleitung und dem Innenleiter 1 der weiterführenden Koaxialleitung. Die Konstruktion des Richtungskoppler ist so ausgeführt, daß der Streifenleiter 3 mit dem Innenleiter 1 gekoppelt ist. Dies erfolgt dadurch, daß der Streifenleiter in einer die Koppelzone freilegende Aussparung 4 des Außenleiters 2 der Koaxialleitung eingepaßt ist. Der Masseleiter 6 der Streifenleitung dient gleichzeitig als Schirmung der Koaxialleitung im Bereich der Aussparung 4.In FIGS. 1a-1c, one constructed according to the invention is constructed Embodiment shown, which relates to a 30 dB coupler, which has a 50 Ω strip line and contains a 50 Ω coaxial line. The inner conductor of the coaxial line is marked with 1, the associated outer conductor with 2 designated. The stripline is applied to a dielectric 5 in a manner known per se Metal foil 3 illustrated. Directional coupling is obtained through a suitable choice of dimensioning between the coupling part 3 of the aforementioned stripline and the inner conductor 1 of the continuing Coaxial line. The construction of the directional coupler is carried out so that the strip conductor 3 with the Inner conductor 1 is coupled. This takes place in that the strip conductor is in a recess that exposes the coupling zone 4 of the outer conductor 2 of the coaxial line is fitted. The ground conductor 6 of the stripline is used at the same time as shielding of the coaxial line in the area of the recess 4.
Die Streifenleitung selbst ist aus fertigungstechnischen Gründen auf eine dieelektrische Trägerplatte 5 (Substrat) aufgebracht, die ihrerseits als getrennter Teil in den Koppler 10 derart eingesetzt werden kann, daß ho der koppelnde Teil 3 in vorbestimmten! Absland k über den Inncnleiter 1 zu liegen kommt. Um die Anordnung nach außen abzuschirmen, wird über den Träger 5 mitThe stripline itself is applied to a dieelectric carrier plate 5 (substrate) for manufacturing reasons, which in turn can be used as a separate part in the coupler 10 so that the coupling part 3 in predetermined! Absland k comes to rest over the inner conductor 1. In order to shield the arrangement from the outside, is on the carrier 5 with

Mit einem derart aufgebauten Richtungskoppler konnten bereits bei einem einfachen Laboraufbau die in der Fig.2 angegebenen Werte für die Koppel- und Sperrdämpfungen erzielt werden.With a directional coupler constructed in this way, the in of the Fig.2 specified values for the coupling and Locking attenuations can be achieved.
