Abstract:
(EN) This filter device (10A) is provided with: a common terminal (Tc); input/output terminals (T1, T2); a filter (11) which is connected to a first path that connects the common terminal (Tc) and the input/output terminal (T1) with each other, and which has a first band as the passband; a filter (12) which is connected to a second path that connects the common terminal (Tc) and the input/output terminal (T2) with each other, and which has a second band as the passband, said second band having frequencies that are different from the frequencies of the first band and do not overlap the frequencies of the first band; a switch (SW1) which is connected between a node (X1) that is on the first path between the filter (11) and the input/output terminal (T1) and a node (X2) that is on the second path between the filter (12) and the input/output terminal (T2); and a switch (SW2) which is connected to the second path between the node (X2) and the input/output terminal (T2).
(FR) La présente invention concerne un dispositif de filtre (10A) qui comporte : une borne commune (Tc) ; des bornes d'entrée/sortie (T1, T2) ; un filtre (11) qui est connecté à un premier trajet qui connecte la borne commune (Tc) et la borne d'entrée/sortie (T1) l'une avec l'autre, et qui a une première bande en tant que bande passante ; un filtre (12) qui est connecté à un second trajet qui connecte la borne commune (Tc) et la borne d'entrée/sortie (T2) l'une avec l'autre, et qui a une seconde bande en tant que bande passante, ladite seconde bande ayant des fréquences qui sont différentes des fréquences de la première bande et ne chevauchent pas les fréquences de la première bande ; un commutateur (SW1) qui est connecté entre un nœud (X1) qui se trouve sur le premier trajet entre le filtre (11) et la borne d'entrée/sortie (T1) et un nœud (X2) qui se trouve sur le second trajet entre le filtre (12) et la borne d'entrée/sortie (T2) ; et un commutateur (SW2) qui est connecté au second trajet entre le nœud (X2) et la borne d'entrée/sortie (T2).
(JA) フィルタ装置(10A)は、共通端子(Tc)、入出力端子(T1およびT2)と、共通端子(Tc)と入出力端子(T1)とを結ぶ第1経路上に接続され、第1帯域を通過帯域とするフィルタ(11)と、共通端子(Tc)と入出力端子(T2)とを結ぶ第2経路上に接続され、第1帯域の周波数と異なり、かつ、第1帯域の周波数と重ならない第2帯域を通過帯域とするフィルタ(12)と、第1経路上であってフィルタ(11)および入出力端子(T1)の間のノード(X1)と、第2経路上であってフィルタ(12)および入出力端子(T2)の間のノード(X2)との間に接続されたスイッチ(SW1)と、第2経路上であってノード(X2)と入出力端子(T2)との間に接続されたスイッチ(SW2)とを備える。
