A phased-array antenna panel has front end modules mounted on a Printed Circuit Board (PCB). Several phased-array processing die, transform phase and gain according to a register array in an RFIC on the PCB. The register array are grouped into a local register group and a global register group. Each set of local registers control an individual antenna element and a global register group controls overall RFIC function. The apparatus elaborates phase shift weights into a submodule of a phased-array antenna system. Each submodule determines its own base phase shift weight per its unique location and configuration to accelerate antenna beam direction changes.
