Abstract (en)

[origin: US2024222839A1] A rat-race balun includes a transmission line loop and 4 input-output ports P1, P2, P3, P4 connected to the transmission line loop, the balun being designed to receive a first signal on the port P1, and to divide the first signal into a second signal that is delivered to the port P2 and a third signal that is delivered to the port P4, the second signal and the third signal being in phase opposition with one another, the balun wherein the balun is kidney-shaped and the ports P2, P4 each comprise at least a first section connected to the transmission line, the first section of the port P2 being parallel to the first section of the port P4.

Abstract (fr)

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, ledit balun étant adapté pour recevoir un premier signal sur le port P₁, et pour diviser ledit premier signal en un deuxième signal délivré sur le port P₂ et un troisième signal délivré sur le port P₄, ledit deuxième signal et ledit troisième signal étant en opposition de phase l'un avec l'autre, ledit balun étant caractérisé en ce que :- le balun présente une forme de haricot et- les ports P₂, P₄ comportent chacun au moins une première section connectée à la ligne de transmission, la première section du port P₂, étant parallèle à la première section du port P₄.
