Title (EN) RADIO FREQUENCY DIRECTIONAL COUPLER
(FR) COUPLEUR DIRECTIF HAUTE FRÉQUENCE
(DE) HOCHFREQUENZ -RICHTKOPPLER
Abstract:
(EN) Radio frequency directional coupler (1), comprising four λ/4 strip lines (11-14) connected in a circuit, the interfaces of which form an input (7), two antenna ports (8, 9) and an output (10), and further comprising at least one controllable impedance (15, 16), which is inserted in a strip line (13, 14) and controlled by a tuning device (17) connected to the output (10) with respect to a minimization of the signal occurring at the output (10) when an input signal is fed at the input (7).
(FR) L'invention concerne un coupleur directif haute fréquence comprenant quatre microbandes λ/4 (11 – 14), montées en cercle, dont les interfaces forment une entrée (7), deux ports d'antenne (8, 9) et une sortie (10). L'invention est caractérisée en ce qu'il est prévu au moins une impédance (15, 16) pouvant être commandée, intercalée dans une microbande (13, 14), et qui est commandée par un dispositif de syntonisation (17) connecté à la sortie (10), en considérant une minimalisation du signal se produisant à la sortie (10) – pour un signal d'entrée généré à l'entrée (7).
(DE) Hochfrequenz-Richtkoppler (1) mit vier im Kreis geschalteten λ/4-Streifenleitern (11 - 14), deren Schnittstellen einen Eingang (7), zwei Antennenports (8, 9) und einen Ausgang (10) bilden, mit zumindest einer in einen Streifenleiter (13, 14) eingeschalteten steuerbaren Impedanz (15, 16), welche von einer an den Ausgang (10) angeschlossenen Abstimmeinrichtung (17) im Hinblick auf eine Minimierung des - bei Einspeisung eines Eingangssignals am Eingang (7) - am Ausgang (10) auftretenden Signals gesteuert ist.
