Coupled amplifier module feed networks for phased array antennas
Abstract
The coupled amplifier module (CAM) lattice is a new type of feed for phased-array antennas that uses far fewer phase shifters than conventional feeds. For example, the CAM feed network for a linear array employs just one phase-shifter; a 2-D rectangular array requires just three phase-shifters. The CAM feed is realized as a periodic lattice of hard-limited amplifiers. Analysis and computer simulation show that the network establishes a linear phase progression. The CAM network's transient response and sensitivity to fabricational imperfections are also analyzed.
