Patent ID: 8072263

Claim:
A signal power control device, comprising: a first amplification channel comprising a first amplifier, a second amplification channel comprising a fixed-gain attenuator in series with a second amplifier, an adder, and an analog gain adjustment means applied to the first amplification channel and the second amplification channel, an input signal being applied to the first amplification channel, and in parallel with the second amplification channel, the outputs of the first and second amplification channels being connected to the inputs of the adder, and the gain adjustment means being suitable for distributing the respective gains of the first amplification channel and the second amplification channel depending on the power of the input signal according to a distribution law, according to which the gain of the second amplification channel is minimal for the lowest input powers, and the gain of the first amplifier channel is minimal for the highest input powers, the gains of the first amplification channel and the second amplification channel being adjusted in a progressive and continuous manner for the intermediate input powers.
