Wideband, large phased array antennas, using analog control for angle scanning, require true time delay (TTD), rather than phase shifters, to avoid squint and other impairments in both the temporal and spatial domains. While digital beamforming may eventually become a viable solution for such high-end systems, photonic technology can currently provide the… CONTINUE READING
