Abstract:
(EN) The present invention is provided with: an antenna terminal 23; a first filter 19A and a second filter 19B that are connected to the antenna terminal 34, branched from each other when viewed from the antenna terminal 34, and have different pass bands; an individual inductor 53, which, when viewed from an antenna terminal 23, is connected in series to a branch point 34w at which the first filter 19A branches from the other filter and becomes independent; and a common inductor 51 that is located between a position between the antenna terminal 23 and the branch point 34w and a reference unit and that is commonly connected in parallel to a filter 19. The first filter 19A has a higher pass band frequency than the other filters, and at the center frequency of the pass band of an own filter, the susceptance when the side of the second filter 19B is viewed from the antenna terminal 23 is greater than the susceptance when the side of the first filter 19A is viewed from the antenna terminal 23.
(FR) La présente invention comporte : une borne d'antenne 23 ; un premier filtre 19A et un second filtre 19B qui sont connectés à la borne d'antenne 34, qui sont ramifiés l'un par rapport à l'autre lorsque vus depuis la borne d'antenne 34, et qui ont des bandes passantes différentes ; un inducteur individuel 53 qui, lorsque vu depuis une borne d'antenne 23, est connecté en série à un point de ramification 34w auquel le premier filtre 19A se ramifie à partir de l'autre filtre et devient indépendant ; et un inducteur commun 51 qui est situé entre une position entre la borne d'antenne 23 et le point de ramification 34w et une unité de référence et qui est généralement connecté en parallèle à un filtre 19. Le premier filtre 19A a une fréquence de bande passante plus élevée que les autres filtres, et à la fréquence centrale de la bande passante d'un filtre propre, la susceptance lorsque le côté du second filtre 19B est vu depuis la borne d'antenne 23 est supérieure à la susceptance lorsque le côté du premier filtre 19A est vu depuis la borne d'antenne 23.
(JA) アンテナ端子23と、アンテナ端子34に接続され、アンテナ端子34からみて互いに分岐しており、通過帯域が互いに異なる第1フィルタ19Aと第2フィルタ19Bと、アンテナ端子23からみて第1フィルタ19Aが他のフィルタから分岐して単独になる分岐点34wと、の間に直列に接続されている個別インダクタ53と、アンテナ端子23と分岐点34wとの間の位置と基準電位との間に位置して、フィルタ19に対して共通に並列接続された共通インダクタ51と、を備える。第1フィルタは、他のフィルタに比べ通過帯域の周波数が高く、自己のフィルタの通過帯域の中心周波数においてアンテナ端子23から第2フィルタ19Bの側をみたときのサセプタンスが、前記アンテナ端子から第1フィルタ19Aの側をみたときのサセプタンスよりも大きい。
