Abstract
A method of calibrating a phased array including an array of antenna elements, RF communication circuits each of which is electrically coupled to a different corresponding antenna element within the array of antenna elements, and a signal feed network that electrically couples a first signal line to second signal lines, wherein each second signal line is electrically coupled to a different corresponding RF communication circuit among the RF communication circuits, the method involving: performing a first phase of a calibration operation, the first phase of the calibration operation involving calibrating the signal feed network independent of the RF communication circuits; and performing a second phase of the calibration operation, the second phase of the calibration operation involving calibrating, independent of the signal feed network, each of the RF communication circuits until all RF communication circuits among the RF communication circuits are calibrated.
