Abstract

A phased-array antenna panel mounts a plurality of front end modules to a Printed Circuit Board. Antenna elements, each controlled by a phased-array processing die, are individually configured to transform phase and gain according to a register array. The register array in each RFIC grouped into a local register group and a global register group, the local registers physically placed close in proximity to RF chains which each correspond to an element of array antenna, whereby each set of local registers control an individual antenna element and a global register controlling overall RFIC function. The apparatus is configured to efficiently elaborate phase shift weights into a submodule of a phase array antenna system. Each subarray phase control submodule recursively elaborates weights to control phase shifters. Pairs of major operators and minor operators are received and transformed. Each submodule determines its own base phase shift weight per its unique configuration.
