Abstract (en)
[origin: FR2911447A1] The amplifier has a CPU for controlling a pilotage stage and a power stage based on a high frequency input signal (RFin), which is applied to the CPU. The CPU has bias circuits (4, 5) for modifying compression points of the stages, where the bias circuits adapt to gain of the stages to increase a power added efficiency of the stages for the modified compression points. The bias circuits respectively adapt to function of the stages. Switches (7, 8) selectively connect a capacitor (C') and an inductor (L') that are mounted in parallel to an output of the power stage.
