The electric supply allows a rapid switching of PIN diodes from their on state to their blocked state while limiting the electric power supplies required, and for that is used a current amplifying loop allowing upon order to bring almost instantaneously the current to the value desired, while maintaining a low consumption at rest, and it is particularly advantageous to associate this system to a low voltage generator allowing to eliminate the minority carriers, since in this case the high voltage generator allows blocking of the diode during longer rest times, and the invention is advantgeously carried out in the form of an integrated circuit, the invention applying mainly to phase shifters for electronic scanning antennas with PIN diodes to the said antennas as well as to radars comprising the said antennas.
