ELECTRONIC PHASE CHANGER Russian patent published in 2013 - IPC H03C3/00 H03H9/66 

FIELD: radio engineering, communication.

SUBSTANCE: electronic phase changer has a synchronisation loop, having a reference 1 generator and a driving 1a generator, a phase detector 4, a control device 5, first and second directional couplers 2 and a reference load 3, a tuned generator 16, a second phase detector 4a, a second control device 5a, a phase generator 6 and third and fourth directional couplers 2, which form a phasing loop together with the driving generator; outputs of the driving 1a generator and tuned generator 16 are connected through directional couplers 2 to corresponding inputs of an antenna radiator.

EFFECT: eliminating phase and amplitude errors in an antenna aperture, input power constraints, preventing power loss.
