1. A phased array antenna comprising:

  • a substrate and a plurality of phased array antenna elements carried by said substrate;

    a plurality of antenna element controllers for said phased array antenna elements; and

    a central controller for communicating with a host and for providing beam steering commands to said antenna element controllers during a normal state, providing a ready signal for placing said antenna element controllers in a synchronization state corresponding to a predetermined time window during which the host will provide an edge trigger synchronization signal, and passing the edge trigger synchronization signal from the host to said antenna element controllers substantially immediately upon receipt thereof and without processing thereof;

    each of said antenna element controllers storing a respective next beam steering command and implementing the respective next beam steering command as a respective active beam steering command responsive to the edge trigger synchronization signal from said central controller.
