Method and a device for controlling amplification of a signal emitted by a mobile terminal and increasing the autonomy of the mobile terminal

摘要

A method of controlling amplification of a signal emitted by a radiocommunication terminal including a power amplifier and a power supply battery includes the steps of detecting the output power of the amplifier and converting the output power into a detected voltage, comparing the detected voltage with a set point voltage, and adapting the input power of the power amplifier as a result of the comparison. The detected voltage and/or the set point voltage is rendered dependent on the voltage of the power supply battery during the step of detecting and converting the output power of the amplifier.
