Claim 0:
1. A device for controlling a scanning active antenna comprising at least two transmission paths, each of the transmission paths comprising a phase control module and a power output amplifier, wherein a radiating element is arranged at an output of each power output amplifier, the device comprising:
at least two voltage modulators, each voltage modulator configured to modulate a drain voltage of one of the power output amplifiers; and
a control device transmitting to the at least two voltage modulators modulating the drain voltage of each output amplifier a respective pulse width modulation signal computed in relation to an altitude and azimuth computation for a desired radiation of the scanning active antenna to manage a gain of each power output amplifier in accordance with a predefined first bias law, a phase applied to the drain of each power output amplifier being controlled in accordance with a second bias law.
