ABSTRACT:
A monostable circuit with device-status feedback control to an external timing terminal is used to controllably change the magnetization state of a ferrite phase shifter core. A pair of such bistable circuits with suitable feedback controls permits a single command pulse of controlled duration to controllably both reset a ferrite core to a saturated magnetic state and then subsequently set the core to a desired non-saturated magnetization state (corresponding to the time duration of the single command pulse). By addition of suitable steering circuits, the controlled resetting and setting of one or more pairs of such ferrite cores can also be achieved using the same single command pulse. The ability to both reset and set plural ferrite phase shifter cores with but a single command pulse of controlled duration permits considerable simplification of beam steering control wiring for a two-dimensional phased array of RF radiators (e.g., so as to provide electronic beam steering control).
