Abstract
L'invention concerne les dispositifs à couplage de charge. La structure de l'invention permet de réaliser un changement de direction à 180 degrés entre deux canaux adjacents 23 et 25 d'une ligne à retard à méandres, avec un rayon de courbure effectif relativement faible, tout en réduisant au minimum les pertes sur le transfert de charge. La faible valeur du rayon de courbure permet de rapprocher les branches adjacentes de la ligne à retard, ce qui permet d'obtenir une ligne de grande longueur sur un substrat d'aire relativement faible. Dans le mode préférentiel représenté, l'axe 34 du canal 27 se trouve sous l'axe 36 du canal 23. La région de transition suivante 38 va en s'élargissant vers le canal 40 d'axe 52. Un second changement de direction à 90 degrés (46, 48, 50) complète celui qui vient d'être décrit. Application aux lignes à retard utilisées en télévision.
