Title (EN) MULTIPORT AMPLIFIER AND WIRELESS DEVICE USING THE SAME
(FR) AMPLIFICATEUR À PORTS MULTIPLES ET DISPOSITIF SANS FIL L’UTILISANT
(JA) マルチポートアンプおよびそれを用いた無線装置
Abstract:
(EN) Provided are a multiport amplifier wherein a communication quality is improved by improving isolation among output terminals, and a wireless device using the multiport amplifier. The multiport amplifier is provided with an input hybrid (3a), an output hybrid (3b), a plurality of amplifiers (7a to 7d) and gain/phase control circuits (4a to 4d) which are inserted between the input hybrid (3a) and the output hybrid (3b), a plurality of connection circuits (8a to 8d) which are inserted between the output hybrid (3b) and the output terminals (9a to 9d) and receive extracted signals (U1 to U4) corresponding to output signals (O1 to O4), and a feedback circuit comprising a frequency selection circuit (13a) inserted between the connection circuits (8a to 8d) and the gain/phase control circuits (4a to 4d).
(FR) La présente invention concerne un amplificateur à ports multiples procurant une qualité de communication améliorée grâce à l’amélioration de l’isolation entre les bornes de sortie, et un dispositif sans fil utilisant ledit amplificateur à ports multiples. L’amplificateur à ports multiples est pourvu d’un coupleur hybride d’entrée (3a), d’un coupleur hybride de sortie (3b), d’une pluralité d’amplificateurs (7a à 7d) et de circuits de commande de gain et de phase (4a à 4d) qui sont insérés entre le coupleur hybride d’entrée (3a) et le coupleur hybride de sortie (3b), d’une pluralité de circuits de connexion (8a à 8d) qui sont insérés entre le coupleur hybride de sortie (3b) et les bornes de sortie (9a à 9d) et reçoivent des signaux extraits (U1 à U4) correspondant à des signaux de sortie (O1 à O4), et un circuit de rétroaction comprenant un circuit de sélection de fréquence (13a) inséré entre les circuits de connexion (8a à 8d) et les circuits de commande de gain et de phase (4a à 4d).
(JA)  出力端子間のアイソレーションを改善して、通信品質を改善したマルチポートアンプおよびそれを用いた無線装置を得る。 この発明に係るマルチポートアンプは、入力ハイブリッド3aと、出力ハイブリッド3bと、入力ハイブリッド3aと出力ハイブリッド3bとの間に挿入された複数の増幅器7a~7dおよび複数の利得・位相制御回路4a~4dと、出力ハイブリッド3bと複数の出力端子9a~9dとの間に挿入されて、複数の出力信号O1~O4に対応した抽出信号U1~U4を受信する複数の結合回路8a~8dと、複数の結合回路8a~8dと複数の利得・位相制御回路4a~4dとの間に挿入された周波数選択回路13aを有する帰還回路とを備えている。
