COMMAND CONTROL DEVICE FOR ANTENNA ARRAY PHASE SHIFTERS Russian patent published in 2008 - IPC H01Q3/30 

FIELD: phased antenna arrays.

SUBSTANCE: proposed device that can be used in electronically scanned arrays incorporating beam control and pattern-shaping systems, phasing system using command method for controlling ferrite phase shifters and polarization switches is designed for building multicomponent antenna assemblies characterized in high beam scanning speed at minimal number of control conductors in antenna assembly and in high operating reliability as well as for reducing array cost due to installation of ferrite phase shifters in array without their pre-selection and sorting-out with respect to phase-time and phase-temperature characteristics for further antenna-by-antenna individual tuning and channel calibration in assembled antenna array to minimize magnetization reversal in ferrite phase shifters and polarization switches by implementing algorithm of reset-pulse individual length adaptive generation including results of measuring magnetizing current pulse length of phase shifter (polarization switch) according to maximal cycle of hysteresis loop. Device has digital data processor unit incorporating random-access FLASH memory, built-in checkup system, circuit for limiting current maximum through power circuit of each current reset switch and installation, temperature senior, universal series channel interface, and through at least each array antenna being phased out, as well as for micro-miniaturization of the entire device to monolithic integrated circuit of SLSIC type built around system-on-chip base.

EFFECT: enhanced beam change-over speed and reliability of array, reduced number of control couplers, minimized energy requirement for reversing magnetization of ferrite phase shifters.
