Title (EN) MULTI-PORT AMPLIFIER AND WIRELESS DEVICE USING 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) A multi-port amplifier and a wireless device using the same wherein the isolation between output terminals has been improved to enhance the communication quality.  The multi-port amplifier comprises: an input hybrid (3a); an output hybrid (3b); a plurality of amplifiers (7a-7d) and a plurality of gain/phase control circuits (4a-4d) inserted between the input hybrid (3a) and the output hybrid (3b); a plurality of output coupling circuits (8a-8d) inserted between the output hybrid (3b) and a plurality of output terminals (9a-9d) for the purpose of receiving output extracted signals (U1-U4) corresponding to a plurality of output signals (O1-O4); and a feedback circuit having a frequency selecting circuit (13a) inserted between the plurality of output coupling circuits (8a-8d) and the plurality of gain/phase control circuits (4a-4d).
(FR) La présente invention concerne un amplificateur à ports multiples et un dispositif sans fil l’utilisant, l’isolation entre les bornes de sortie ayant été améliorée pour une meilleure qualité de communication. L’amplificateur à ports multiples comprend : un coupleur hybride d’entrée (3a) ; un coupleur hybride de sortie (3b) ; une pluralité d’amplificateurs (7a à 7d) et une pluralité de circuits de commande de gain et de phase (4a à 4d) insérés entre le coupleur hybride d’entrée (3a) et le coupleur hybride de sortie (3b) ; une pluralité de circuits de couplage de sortie (8a à 8d) insérés entre le coupleur hybride de sortie (3b) et une pluralité de bornes de sortie (9a à 9d) dans le but de recevoir des signaux extraits de sortie (U1 à U4) correspondant à une pluralité de signaux de sortie (O1 à O4) ; et un circuit de rétroaction comportant un circuit de sélection de fréquence (13a) inséré entre la pluralité de circuits de couplage de sortie (8a à 8d) et la pluralité de 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に対応した出力抽出信号U1~U4を受信する複数の出力結合回路8a~8dと、複数の出力結合回路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。
