Abstract

L'invention concerne un dispositif de partage d'antennes qui utilise un filtre diélectrique (11) du côté de la transmission et un filtre à onde acoustique de surface du côté de la réception. L'interférence entre le filtre côté réception et le filtre côté transmission provoquée par l'utilisation de différents types de filtres est ajustée par un ajusteur de phases (16). Ceci permet de minimiser la perte de puissance d'un signal de transmission et la baisse de la sensibilité de réception. Ainsi, la perte de puissance de transmission est réduite par le biais d'un ajustement de phases réalisé par l'ajusteur de phases (16) et la diminution de la sensibilité de réception est réduite uniquement au moyen du filtre à onde acoustique de surface au niveau de la réception.
