Abstract

L'invention concerne un circuit d'aiguillage pour des ondes électromagnétiques courtes et très courtes. Dans ce circuit d'aiguillage comportant un coupleur directif K raccordé à une antenne 1 et à des émetteurs S1, S2, une branche D du coupleur directif K est fermée par un réseau N de résistances complexes dont la structure et le dimensionnement sont choisis de manière qu'il existe un découplage maximum, entre les deux autres branches A, B du coupleur directif, dans une plage prédéterminée de fréquences de travail. Application notamment aux circuits d'aiguillage de plusieurs émetteurs à une antenne commune.
