Title (EN) FRONT-END MODULE AND COMMUNICATION DEVICE
(FR) MODULE FRONTAL ET DISPOSITIF DE COMMUNICATION
(JA) フロントエンドモジュールおよび通信装置
Abstract:
(EN) This front-end module (1) is provided with a front-end circuit (4B) that propagates a signal in a band Ba in a CA mode, and a front-end circuit (4A) that propagates a signal in a band Bb, wherein the front-end circuit (4A) is provided with a quadplexer (70A) for the bands Ba and Bb, the front-end circuit (4B) is provided with a quadplexer (30B) for the bands Ba and Bb, and an impedance-variable circuit (40) connected to a band Bb transmission terminal of the quadplexer (30B). In the CA mode, the impedance-variable circuit (40) serves as a reflection circuit that reflects a band Bb transmission wave, and in a non-CA mode, the impedance-variable circuit (40) serves as a matching circuit that propagates or absorbs the band Bb transmission wave.
(FR) L'invention concerne un module frontal (1) pourvu d'un circuit frontal (4B) qui propage un signal dans une bande Ba dans un mode CA et d'un circuit frontal (4A) qui propage un signal dans une bande Bb, le circuit frontal (4A) est pourvu d'un quadriplexeur (70A) pour les bandes Ba et Bb, le circuit frontal (4B) est pourvu d'un quadriplexeur (30B) pour les bandes Ba et Bb et d'un circuit à impédance variable (40) connecté à un terminal de transmission de bande Bb du quadriplexeur (30B). Dans le mode CA, le circuit à impédance variable (40) sert de circuit de réflexion qui réfléchit une onde de transmission de bande Bb, et dans un mode non-CA, le circuit à impédance variable (40) sert de circuit d'adaptation qui propage ou absorbe l'onde de transmission de bande Bb.
(JA) フロントエンドモジュール(1)は、CAモードにおいてバンドBaの信号を伝搬するフロントエンド回路(4B)およびバンドBbの信号を伝搬するフロントエンド回路(4A)を備え、フロントエンド回路(4A)は、バンドBaおよびBbのクワッドプレクサ(70A)を備え、フロントエンド回路(4B)は、バンドBaおよびBbのクワッドプレクサ(30B)と、クワッドプレクサ(30B)のバンドBb送信端子に接続されたインピーダンス可変回路(40)とを備え、CAモードの場合、インピーダンス可変回路(40)はバンドBb送信波を反射する反射回路となり、非CAモードの場合、インピーダンス可変回路(40)はバンドBb送信波を伝搬または吸収する整合回路となる。
