Abstract:
(EN) The purpose of the present invention is to adjust the frequency of an attenuation pole while maintaining the pass band of a laminated balun. The laminated balun (100) according to the present invention is provided with a first terminal (P1), a second terminal (P2), a third terminal (P3), a first inductor (L11), a second inductor (L13), and an open line conductor (171). The first inductor (L11) is connected between the first terminal (P1) and grounding points (G41-G43). The second inductor (L13) is connected between the second terminal (P2) and the third terminal (P3), and is magnetically coupled to the first inductor (L11). One end (T71) of the open line conductor (171) is an open end, and the other end (T72) of the open line conductor (171) is connected to a via conductor pattern (V61), which is a signal path between the first terminal (P1) and the grounding points (G41, G42).
(FR) L'objectif de la présente invention est d'ajuster la fréquence d'un pôle d'atténuation tout en maintenant la bande passante d'un symétriseur stratifié. Le symétriseur stratifié (100) selon la présente invention est pourvu d'une première borne (P1), d'une deuxième borne (P2), d'une troisième borne (P3), d'une première inductance (L11), d'une seconde inductance (L13) et d'un conducteur de ligne ouvert (171). La première inductance (L11) est connectée entre la première borne (P1) et des points de mise à la terre (G41-G43). La seconde inductance (L13) est connectée entre la deuxième borne (P2) et la troisième borne (P3) et couplée magnétiquement à la première inductance (L11). Une extrémité (T71) du conducteur de ligne ouvert (171) est une extrémité ouverte et l'autre extrémité (T72) du conducteur de ligne ouvert (171) est connectée à un motif conducteur de trou d'interconnexion (V61), qui est un trajet de signal entre la première borne (P1) et les points de mise à la terre (G41, G42).
(JA) 積層バランの通過帯域を維持しながら、減衰極の周波数を調整する。本発明に係る積層バラン(100)は、第1端子(P1)と、第2端子(P2)と、第3端子(P3)と、第1インダクタ(L11)と、第2インダクタ(L13)と、開放線路導体(171)とを備える。第1インダクタ(L11)は、第1端子(P1)と接地点(G41~G43)との間に接続されている。第2インダクタ(L13)は、第2端子(P2)と第3端子(P3)との間に接続され、第1インダクタ(L11)と磁気結合する。開放線路導体(171)は、一方端(T71)が開放端であるとともに、他方端(T72)が第1端子(P1)と接地点(G41,G42)との間の信号路であるビア導体パターン(V61)に接続されている。
