Abstract

La présente invention concerne un pont asymétrique à 3 dB avec une bande de cadre, comprenant une bande de ligne de couplage principale et une bande de ligne de couplage secondaire. La bande de ligne de couplage principale comprend une première bande principale rectangulaire; les deux extrémités de la première bande principale rectangulaire sont respectivement étendues à deux côtés pour former des premières bandes incurvées en forme de L; l'extrémité libre de chaque première bande incurvée est étendue pour former une seconde bande incurvée en forme de L; la seconde bande incurvée sur un côté est étendue pour former une première extrémité d'entrée, et la seconde bande incurvée sur l'autre côté est étendue pour former une première extrémité de sortie. Au moyen du pont, le couplage est optimisé, et de meilleurs effets de couplage peuvent être obtenus dans une plage de fréquences comprise entre 0,8 Ghz et 2,8 Ghz; la différence de phase entre un trajet S21 et un trajet S31 n'est pas supérieure à ± 5°, et satisfait à l'exigence pour une différence de phase de 90° pour un pont 3 dB.
