Title (EN) METHOD AND DEVICE FOR POWER AMPLIFICATION AND BASE STATION
(FR) PROCÉDÉ ET DISPOSITIF POUR L’AMPLIFICATION DE PUISSANCE ET STATION DE BASE
(ZH) 一种功率放大方法、装置和基站
Abstract: front page image
(EN)A method and a device (82) for power amplification and a base station. The device (82) for power amplification includes a first power amplifier module (103), a second power amplifier module (104), a first electric bridge (106), a second electric bridge (107) and a grid voltage module (105). The grid voltage module (105) varies a grid bias voltage provided to the first power amplifier module (103) or the second power amplifier module (104) based on a command or a to-be-amplified signal so as to switch the operating mode of the device (82) for power amplification between a balanced power amplifying mode and a Doherty power amplifying mode.
(FR)L’invention se rapporte à un procédé et un dispositif (82) pour l’amplification de puissance, ainsi qu’à une station de base. Ledit dispositif (82) pour l’amplification de puissance comprend un premier module amplificateur de puissance (103), un second module amplificateur de puissance (104), un premier pont électrique (106), un second pont électrique (107) et un module à tension de grille (105). Ce dernier fait varier la tension de polarisation de grille qui est transmise au premier module amplificateur de puissance (103) ou au second module amplificateur de puissance (104), et ce, grâce à une commande ou à un signal à amplifier. Le but est de changer le mode de fonctionnement du dispositif (82) afin qu’il passe d’un mode d’amplification de puissance compensé à un mode d’amplification de puissance Doherty et inversement.
