摘要
A system substantially updates all the phase shifter values of a phased array antenna by using two “global writes” to update these parameters to all phased-array transformation circuits simultaneously via a serial bus. Antenna elements, each controlled by a phased-array transformation circuit, are individually configured to transform phase and gain according to a register array. The register array has a local register group and a central 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 central register controlling overall beam steering function. Gain values are hierarchically distributed. The apparatus is configured to efficiently elaborate phase shift weights into a submodule of a phase array antenna system with low noise and bandwidth.
