Abstract

L’invention concerne un balun Rat-Race comprenant une boucle de ligne de transmission et 4 ports d’entrée-sortie P1, P2, P3, P4 connectés à ladite boucle de ligne de transmission, la section de ligne de transmission respectives entre les ports adjacents P1 et P4 est de longueur électrique , d’impédance Z 3 et est une section de ligne chargée par un condensateur de capacité C2 ; où < 135 et les égalités suivantes sont vérifiées : et w étant égal à, avec f la fréquence de fonctionnement, et Z P1P4 étant l’impédance de la section de ligne de transmission non chargée de longueur physique 3λ/4 équivalente à ladite section de ligne chargée. Figure pour l’abrégé : Fig. 3
