Abstract
(EN)
The present invention inhibits a harmonic component of a signal passing through a relatively low-frequency passband filter from adversely affecting the filter characteristics of a relatively high-frequency passband filter. A high-frequency module (1) is provided with a first switch (4), an attenuating filter (3), and a plurality of passband filters (12A to 12C, 22A to 22C). The first switch (4) is capable of connecting a common terminal (40) with selected terminals (41, 42) among a plurality of selected terminals (41 to 43) simultaneously. The plurality of passband filters (12A to 12C, 22A to 22C) include a first passband filter (22A) and a second passband filter (22B). The attenuating filter (3) includes a reactance element of at least one of an inductive element and a capacitive element. In the high-frequency module (1), the reactance element is adjacent to at least one of the plurality of passband filters (12A to 12C, 22A to 22C).

La présente invention empêche une composante harmonique d'un signal passant à travers un filtre passe-bande à fréquence relativement basse d'affecter négativement les caractéristiques de filtrage d'un filtre passe-bande à fréquence relativement élevée. Un module haute fréquence (1) est pourvu d'un premier commutateur (4), d'un filtre d'atténuation (3) et d'une pluralité de filtres passe-bande (12A à 12C, 22A à 22C). Le premier commutateur (4) peut connecter simultanément une borne commune (40) à des bornes sélectionnées (41, 42) parmi une pluralité de bornes sélectionnées (41 à 43). La pluralité de filtres passe-bande (12A à 12C, 22A à 22C) comprennent un premier filtre passe-bande (22A) et un second filtre passe-bande (22B). Le filtre d'atténuation (3) comporte un élément de réactance d'un élément inductif et/ou d'un élément capacitif. Dans le module haute fréquence (1), l'élément de réactance est adjacent à au moins un filtre parmi la pluralité de filtres passe-bande (12A à 12C, 22A à 22C).
