CA 2298711

A device and method for controlling an output power level in a mobile communication terminal. The device includes an RSSI detector for detecting a strength of a signal received from a base station, and a controller having a memory for storing bias voltage control values and bias current control values corresponding to strengths of received signals, wherein the controller reads the corresponding bias voltage control value and bias current control value in response to the detected signal strength and supplies the read values to a power amplifier.

L'invention concerne un dispositif et un procédé pour réguler le niveau de puissance dans un terminal de communication mobile. Le dispositif comprend un détecteur de l'indicateur de l'intensité de signal reçu (RSSI), qui sert à détecter l'intensité d'un signal reçu d'une station de base, et un contrôleur muni d'une mémoire servant à stocker les valeurs de contrôle de la tension de polarisation et les valeurs de contrôle du courant de polarisation, qui correspondent à l'intensité des signaux reçus. Le contrôleur lit les valeurs correspondantes de la tension et du courant de polarisation en réponse à l'intensité de signal détectée et fournit les valeurs lues à un amplificateur de puissance.
