Abstract
A set of phase shifters associated with an array of radiators of an electronically scanning antenna are each controlled by a current-limiting amplifier which has an input stage in series with an electronic switch and an output stage connected to a source of operating voltage normally blocking a pair of diodes in the associated phase shifter. A feedback loop between the two amplifier stages includes another diode serving to stabilize the current flow through the phase-shifter diodes upon closure of the electronic switch by a control device and triggering of the input stage by a signal from a reference-voltage generator.
