Abstract
(EN)
The present invention comprises: a main line path (11) through which a main signal (31) flows; an auxiliary line path (12) through which an auxiliary signal (32) flows, the auxiliary signal (32) corresponding to the main signal (31) according to electromagnetic coupling with the main line path (11); and an inductor (13) which is connected in series to one of the main line path (11) and the auxiliary line path (12), and through which one of the main signal (31) and the auxiliary signal (32) flows. A first portion (41) of first wiring (21) constituting the inductor (13) and a second portion (42) of second wiring (22) constituting the other of the main line path (11) and the auxiliary line path (12) are electromagnetically coupled.

La présente invention comprend : un trajet de ligne principale (11) à travers lequel circule un signal principal (31) ; un trajet de ligne auxiliaire (12) à travers lequel circule un signal auxiliaire (32), le signal auxiliaire (32) correspondant au signal principal (31) en fonction d'un couplage électromagnétique avec le trajet de ligne principale (11) ; et une bobine d'induction (13) qui est connectée en série à un des trajets parmi le trajet de ligne principale (11) et le trajet de ligne auxiliaire (12), et à travers laquelle circule un des signaux parmi le signal principal (31) et le signal auxiliaire (32). Une première partie (41) d'un premier câblage (21) constituant la bobine d'induction (13) et une seconde partie (42) d'un second câblage (22) constituant l'autre trajet parmi le trajet de ligne principale (11) et le trajet de ligne auxiliaire (12) sont couplées électromagnétiquement.
