Abstract
A reconfigurable power amplifier includes at least one amplification circuit (E1, E2), and a circuit (6) for controlling the amplification circuit so as to adapt its operation according to an applied input signal (RFin). The circuit for controlling includes a circuit (4, 5) for modifying the compression point of the amplification circuit and for adapting the gain of the amplification circuit in such a manner as to increase the power added efficiency of the circuit for the modified compression point.
