Method and device for adjusting the amplification of a signal transmitted by a mobile terminal in order to increase battery life

摘要

The procedure for the monitoring of an amplification signal emitted from a radio-communication terminal comprising a power amplifier (1) and voltage supply battery (10) entails the detection of the output power (Pout) of the amplifier and converting this power into a detected voltage (Vdet) and comparing this with a reference voltage (Vref). At least one of the detected or reference voltages is produced depending upon the voltage of the supply battery and this before the stage of comparing the detected voltage with the reference voltage. An Independent claim is included for a device for the monitoring of an amplification signal emitted from a radio-communication terminal.
