Title (EN) HIGH-FREQUENCY MODULE AND COMMUNICATION DEVICE
(FR) MODULE HAUTE FRÉQUENCE ET DISPOSITIF DE COMMUNICATION
(JA) 高周波モジュール及び通信装置
Abstract:
(EN) A high-frequency module (1) provided with an LNA (40) is provided with: an HPF circuit (10) which filters an input high-frequency signal; a switch IC (20) which performs a prescribed operation, and which outputs a signal obtained by superimposing the high-frequency signal filtered by the HPF circuit (10) and a direct current bias; and a matching circuit (30) disposed between the switch IC (20) and the LNA (40). The LNA (40) is connected to the switch IC (20) without the interposition of a capacitor, and a signal input from the switch IC (20) via the matching circuit (30) is amplified at an operating point determined by the direct current bias superimposed on the signal.
(FR) Cette invention concerne un module haute fréquence (1) pourvu d'un amplificateur à faible bruit (LNA) (40) comprenant : un circuit de filtre passe-haut (HPF) (10) qui filtre un signal d'entrée haute fréquence ; un circuit intégré (CI) de commutation (20) qui effectue une opération prescrite, et qui délivre un signal obtenu par superposition du signal haute fréquence filtré par le circuit de filtre passe-haut (10) et d'une polarisation en courant continu ; et un circuit d'adaptation (30) disposé entre le circuit intégré de commutation (20) et l'amplificateur à faible bruit (40). L'amplificateur à faible bruit (40) est connecté au circuit intégré de commutation (20) sans interposition d'un condensateur, et un signal entré à partir du circuit intégré de commutation (20) par l'intermédiaire du circuit d'adaptation (30) est amplifié à un point de fonctionnement déterminé par la polarisation en courant continu superposée au signal.
(JA) LNA(40)を備える高周波モジュール(1)であって、入力された高周波信号をフィルタリングするHPF回路(10)と、所定の動作をするスイッチIC(20)であって、HPF回路(10)でフィルタリングされた高周波信号と直流バイアスとが重畳された信号を出力するスイッチIC(20)と、スイッチIC(20)とLNA(40)との間に配置された整合回路(30)と、を備え、LNA(40)は、キャパシタを介することなくスイッチIC(20)と接続され、当該スイッチIC(20)から整合回路(30)を介して入力された信号を、当該信号に重畳されている直流バイアスによって定まる動作点で増幅する。
