Patent

CA 2280870

The present invention relates to n-port junction devices for processing modulated digital RF signals, n being an integer larger than 3, the n-port junction device comprising two RF input ports (4, 5) two passive signal-combining means (2, 3) connected to each other wherein respectively one of the passive signal-combining means (2, 3) is connected to one of the RF inputs (4, 5), and at least two power sensors (P1, P2) wherein each of the passive signal-combining means (2, 3) has at least an output port (6, 7) and each output port (6, 7) is connected to a power sensor (P1, P2). The two passive signal-combining means (2, 3) are connected with each other by means of a phase shifting element (10).

L'invention concerne des appareils de jonction à n-accès pour traiter des signaux RF numériques modulés, n étant un entier supérieur à 3. L'appareil de jonction à n-accès comprend deux bornes d'entrée RF 84, 5), deux éléments de combinaison de signaux (2, 3) passifs, interconnectés, un des ces éléments de combinaison de signaux (2, 3) passifs étant connecté à une des bornes RF (ç, 5), et au moins deux capteurs de puissance (P1, P2). Chacun des éléments de combinaison de signaux (2, 3) passifs comporte au moins une borne de sortie (6, 7) et chaque borne de sortie (6, 7) est reliée à un capteur de puissance (P1. P2). Les deux éléments de combinaison de signaux (2, 3) passifs sont interconnectés par l'intermédiaire d'un élément déphaseur (10).
