Problems solved by technology

[0006] However, the greater the transmission power, the greater the amplification of the terminal, so the terminal also needs a larger battery
This results in a large drain on the battery and thus the duration of the phone is significantly reduced

Embodiment Construction

[0026] figure 1 Briefly shows a device capable of applying the amplification control method of a signal transmitted by a mobile terminal, such as a portable phone, according to the background art.

[0027] Signal amplification is performed by a power amplifier (1) powered by constant input power (Pin), which comes from a pre-amplifier (not shown), and output power (Pout) is transmitted through the mobile terminal antenna 2.

[0028] The mechanism also includes an output power detection and conversion device 3 of the power amplifier 1 . The detecting means 3 detects the output power (Pout) of the power amplifier 1 and then converts it into a voltage (Vdet) corresponding to the detected voltage at the output of the detecting and converting means 3 .

[0029] Said detection output voltage (Vdet) is then sent to comparator 4 in a known manner.

[0030] The comparator 4 comprises two variable resistors 5a, 5b, each of which may be a variable capacitor 6, and an operational amplif...

Abstract

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.

Description

technical field [0001] The invention relates to a wireless terminal, such as a portable wireless phone, and in particular to a method and device for controlling the amplification and control of a signal transmitted by a mobile terminal capable of reducing the energy consumption of the terminal's power supply battery. Background technique [0002] Mobile terminals of the portable telephone type have a power amplifier capable of transmitting a signal with sufficient power for communication. [0003] We know that every telephone must constantly be connected to a terminal in order to make and receive calls. The farther the phone is from the terminal, the greater the transmit power must be. [0004] According to the GSM network specification (Global System for Mobile communications Global System for Mobile Communications), a terminal operating on the network must be able to transmit a maximum power of 33dBm. This maximum power can be reduced to 30.5dBm in extreme cases, that is...
