Abstract
A system and method are provided for calibrating and programming a phased array antenna. The system includes a calibration module configured to generate calibrated constellation control codes corresponding to a desired constellation, a look-up table (LUT) for storing the calibrated constellation control codes, and a processing unit configured to program beamforming integrated circuits (BFICs) to produce an RF radiated signal having the desired constellation. A characterization subsystem is configured to capture a characterization subset of the phased array antenna.
