An apparatus substantially updates all the phase shifter values of a phased array antenna by using “global write” 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. The apparatus is configured to efficiently elaborate phase shift weights into a submodule of a phase array antenna system with low noise and bandwidth.

A method for operating a beam-steering system includes receiving a signal to be tracked, generating a first phase-mode signal, a second phase-mode signal and a third phase-mode signal from the received signal, and generating a first intermediate auxiliary signal, a second intermediate auxiliary signal, and a first intermediate main signal in accordance with the phase-mode signals. The method also includes deriving a first steering signal proportional to a circumferential steering angle of the received signal from the first intermediate main signal and the first auxiliary signal, and deriving a second steering signal proportional to a radial steering angle of the received signal from the second intermediate auxiliary signal and the first intermediate main signal.
