Abstract

A power divider for microwaves, having a microwave conductor which is split into two arms which form an acute angle with one another at the division point, one arm (2) or both arms (2, 3) in each case forming a direction coupler (2, 5 and 3, 4) with a further conductor (4, 5). <IMAGE>

Description

Die Erfindung betrifft einen Leistungsteiler nach dem Oberbegriff des Anspruchs 1. Solche Leistungsteiler sind als "Wilkinson-Teiler" bekannt. Zur Mehrfachteilung von Mikrowellenleistungen werden z.B. mehrere Wilkinson-Teiler hintereinandergeschaltet. Dies erfordert einen großen Raumbedarf. Es ist weiter bekannt, Leistungen mit Richt­ kopplern aufzuteilen.The invention relates to a power divider according to the Preamble of claim 1. Such power dividers are known as the "Wilkinson Divider". For multiple division of Microwave powers are e.g. several Wilkinson dividers connected in series. This requires a big one Space requirements. It is also known to provide benefits with direction split couplers.

Aufgabe der Erfindung ist es, einen Leistungsteiler der eingangs genannten Art zur Mehrfachaufteilung anzugeben, der raumsparend und billig ist. Die Lösung dieser Aufgabe ist dem Patentanspruch zu entnehmen.The object of the invention is to provide a power divider specify the type mentioned above for multiple splitting, that is space-saving and cheap. The solution to this The task can be found in the patent claim.

Die Erfindung wird im folgenden anhand eines in der Figur dargestellten Ausführungsbeispiels näher erläutert. Die Figur zeigt einen in Streifenleitungstechnik ausgeführten Vierfach-Teiler. Der Eingangsleiter 1 mit der Impedanz Zo teilt sich auf in zwei Arme 2 und 3, die am Teilungspunkt einen spitzen Winkel miteinander bilden. Diese Konfigu­ ration stellt einen an sich bekannten "Wilkinson-Teiler" dar. Erfindungsgemäß erfolgt eine weitere Leistungsteilung dadurch, daß die Arme 2, 3 mit weiteren Streifenleitungen 4, 5 Richtkoppler bilden. Dadurch ergibt sich ein Mehrfach- Leistungsteiler, der besonders platzsparend ist und zudem billig herzustellen ist.The invention is explained below with reference to an embodiment shown in the figure. The figure shows a quadruple divider implemented in stripline technology. The input conductor 1 with the impedance Zo is divided into two arms 2 and 3 , which form an acute angle with one another at the division point. This configuration configures a known "Wilkinson divider". According to the invention, power is divided further in that the arms 2 , 3 form further strip lines 4 , 5 directional couplers. This results in a multiple power divider that is particularly space-saving and is also inexpensive to manufacture.

Die Streifenleiter der Richtkoppler 2, 5 bzw. 3, 4 sind in an sich bekannter Weise so zu dimensionieren, daß sich der gewünschte Koppelfaktor und entsprechende Leistungsauf­ teilung ergeben. Alle Ausgänge OUT 1 bis 4 enden in Leitern mit der Impedanz Zo. Die Leiter sind, soweit erforderlich, mit Widerständen 2 Zo abgeschlossen.The stripline of the directional coupler 2 , 5 and 3 , 4 are dimensioned in a manner known per se so that the desired coupling factor and corresponding power distribution result. All outputs OUT 1 to 4 end in conductors with the impedance Zo . If necessary, the conductors are terminated with resistors 2 Zo .

Der erfindungsgemäße Mehrfach-Leistungsteiler ist auch in jeder anderen Leitungstechnik, z.B. in Finleitungstechnik, realisierbar.The multiple power divider according to the invention is also in any other line technology, e.g. in fine line technology, realizable.
