Abstract

La présente invention concerne un combinateur de puissance avec des caractéristiques de filtre passe-bas comprises dans celui-ci. Le combinateur de puissance comprend un filtre passe-bas qui permet à une bande basse prédéterminée uniquement de passer à travers celui-ci, combine des signaux de puissance élevée avec une structure de jonction en T à l'aide d'un motif de micro-bande et émet uniquement une bande de fréquence souhaitée en tant que signal de sortie final lorsque les signaux combinés passent à travers le filtre passe-bas. Lors de l'application de la structure d'un mode de réalisation de la présente invention, des sorties générées au niveau d'un amplificateur de puissance élevée multicanal sont combinées en passant à travers le combinateur de puissance, et il est possible d'utiliser, en tant que sortie finale, des signaux dans lesquels même les composantes harmoniques sont supprimées lorsque les signaux combinés passent à travers le filtre passe-bas.
