1. A method for regulating the transmission power of a transmitter system (5-7) incorporated in an electronic module (1) of an automobile, wherein a transmitter system (5-7) is produced which comprises an amplification stage (5) having an adjustable amplification gain designed so that the transmission power extends in a predetermined range of operating powers, and in that:

  • in a phase prior to the operation of the electronic module (1);

    a compensation table for the transmitter system (5-7) is established and stored, which is representative of the amplification gains to be applied to maintain a constant transmission power in a predetermined range of operating powers, according to the value of external parameters representative of the environment of the transmitter system (5-7), such that, in particular, the temperature in the electronic module (1), the electrical power supply voltage of said transmitter system,and the value of the offset of the amplification stage is measured and stored for the electronic module (1),and, during the operation of an electronic module (1), in order to obtain a given transmission power, the external parameters representative of the environment of the transmitter system (5-7) are periodically measured, and an amplification gain is determined and applied that is on the one hand designed to compensate the offset of the amplification stage (5), and on the other hand adjusted according to the environment by the use of the compensation table.
