Abstract
Embodiments include systems and methods for fine control of beam steering for wide band wireless applications using a phased array of antenna elements. In one embodiment, a digitally controlled delay line delays the signal output from a modulator in each branch of multiple branches feeding multiple antennas in an array. An output of the digital delay line is input to a digital to analog converter. A second digital delay line also delays the signal within the digital to analog converter. The manner of implementation of the delays enables accurate production of a steered beam at a high data rate.
