Abstract
La présente invention concerne un circuit balun (1B) comportant un premier sous-circuit (10) et un second sous-circuit (20) chacun correspondant au moins sensiblement à un guide d'onde .lambda./4. Le premier sous-circuit (10) comprend un premier conducteur (10U), un second conducteur (10L) et une couche diélectrique disposée entre les premier et second conducteurs, ces conducteurs étant connectés l'un à l'autre de manière capacitive et inductive. Le second sous-circuit (20) comprend un premier conducteur (20U), un second conducteur (20L) et une couche diélectrique disposée entre les premier et second conducteurs, ces conducteurs étant connectés l'un à l'autre de manière capacitive et inductive. Un premier côté du premier conducteur (10U) situé dans le premier sous-circuit (10) est connecté à un port d'entrée (P1). Un second côté du premier conducteur (10U) situé dans le premier sous-circuit (10) est connecté à un premier côté du premier conducteur (20U) situé dans le second sous-circuit (20) au moyen d'un conducteur de connexion (15). Un second côté du second conducteur (10L) situé dans le premier sous-circuit (10) est connecté à un premier port de sortie (P2). Un premier côté du second conducteur (20L) situé dans le second sous-circuit (20) est connecté à un second port de sortie (P3). Une premier raccordement de guide d'onde .lambda./4 ouvert (30) est connecté à un second côté du second conducteur (10L) situé dans le premier sous-circuit (10), et un second raccordement de guide d'onde .lambda./4 (40) ouvert est connecté à un second côté du second conducteur (20L) situé dans le second sous-circuit (20).
