Abstract
A system for adapting the voltage of a drain of a power stage includes at least two transmission paths TXa, a transmission path comprising a resistive element (1n), a phase control module (2n), and a power stage (3n) at the output of which a radiating element (En) is arranged, comprising at least: a device (5n) for determining the value of a reflected power Pr, the value of an incident power Pi in a power stage, and the ratio of the powers R, an analogue device (6n) configured so as to pulse width-modulate the difference signal, a switching cell (7n) receiving a low-power PWM signal and designed to generate a power signal PWMa that is transformed, by a low-pass filter (8n), into a bias signal for biasing the power stage in accordance with a predefined bias control law.
