Patent attributes
A device for controlling least two peak power levels for an amplifier operating in pulse mode, comprising a premodulation stage and a power-locked stage. The premodulation stage has a first amplifier stage, having at least one amplifier (1) and one processing device (8) suitable for supplying a squarewave signal to the amplifier (1), and a second amplifier stage, having at least one amplifier (7) and one processing device (9) suitable for supplying a signal having a shape roughly identical to the shape of the applied modulation. The power-locked stage has a coupler and detector (11) for sampling at least a part of the signal at the output of the amplification subsystem and sending it to a video amplifier (22). A peak detector (24) and a level discriminator (25) are suitable for generating a modulation signal to an amplifier (20) and power supply means (21, 22, 23) are supplied for the amplifiers.
