Title (EN) HYBRID-BASED CANCELLATION IN PRESENCE OF ANTENNA MISMATCH
(FR) ANNULATION À BASE D'HYBRIDES EN PRÉSENCE D'UNE DÉSADAPTATION D'ANTENNE
Abstract: front page image
(EN)A multi-port hybrid-based cancellation network may include a first and second hybrid coupler, and a first and second two-port network. The second hybrid coupler may be distinct from the first hybrid coupler. The first two-port network may include a first filter connected between the first and the second hybrid couplers. The second two- port network may include a second filter that is distinct from but essentially the same as the first filter connected between the first and the second hybrid couplers. Other circuitry components may be connected to one of the ports of multi-port hybrid-based cancellation network. These other circuitry components may have a configuration that increases or maximizes signal isolation between at least two of the ports of the multi-port hybrid-based cancellation network.
(FR)L'invention concerne un réseau d'annulation à base d'hybrides multiport, qui peut comprendre un premier et un second coupleur hybride, et un premier et un second réseau à deux ports. Le second coupleur hybride peut être distinct du premier coupleur hybride. Le premier réseau à deux ports peut comprendre un premier filtre connecté entre les premier et second coupleurs hybrides. Le second réseau à deux ports peut comprendre un second filtre, qui est distinct du premier port mais est essentiellement le même que lui, connecté entre les premier et second coupleurs hybrides. D'autres composants de circuit peuvent être connectés à l'un des ports du réseau d'annulation à base d'hybrides multiport. Ces autres composants de circuit peuvent avoir une configuration qui augmente ou qui maximise l'isolation de signal entre au moins deux des ports du réseau d'annulation à base d'hybrides multiport.
