Title
(EN) WIRELESS DEVICE WITH A MULTI-TURN DIRECTIONAL COUPLER
(FR) DISPOSITIF SANS FIL À COUPLEUR DIRECTIONNEL À SPIRES MULTIPLES
Abstract
(EN)
A directional coupler disclosed herein may include a main line provided on a substrate, the main line having a first end connected to an input port and a second end connected to an output port. The coupler may include a coupled line disposed on the substrate, the coupled line having a first end connected to a coupled port and a second end to an isolated port. The main line is electrically isolated from the coupled line. The coupled line includes multiple turns forming a winding, and a portion of the winding overlaps with the main line. The coupled line forms a plurality of windings inductively coupled with the main line. The main line and the coupled line are routed to propagate electric signals on both lines in a same direction, and enhance inductive coupling by mutual inductance.

L'invention concerne un coupleur directionnel qui peut comprendre une ligne principale disposée sur un substrat, la ligne principale ayant une première extrémité connectée à un port d'entrée et une seconde extrémité connectée à un port de sortie. Le coupleur peut comprendre une ligne couplée disposée sur le substrat, la ligne couplée ayant une première extrémité connectée à un port couplé et une seconde extrémité connectée à un port isolé. La ligne principale est isolée électriquement de la ligne couplée. La ligne couplée comprend de multiples spires formant un enroulement, et une partie de l'enroulement chevauche la ligne principale. La ligne couplée forme une pluralité d'enroulements couplés de manière inductive à la ligne principale. La ligne principale et la ligne couplée sont acheminées pour propager des signaux électriques sur les deux lignes dans une même direction, et améliorer le couplage inductif par inductance mutuelle.
