Abstract

A diode phase-shifting device for an electronically scanning antenna includes a cut-off device designed to operate when the phase-shifting diodes are switched to their non-conducting state, with a view to increasing the switchover speed. This device comprises mainly a low-voltage generator, a circuit breaker or switch, and a high-voltage generator. A switching from the low-voltage generator to the high-voltage generator occurs when the voltage at the terminals of the phase-shifting diode considered exceeds a given threshold value.
