Combining The Best Of Both Worlds: True Time Delays And Phase Shifters

By Bilgin Kiziltas, Field Applications Engineer, ADI

Electronically scanned arrays (ESAs) utilize PSs or TTDs or a mix of both to point the summed beam toward the desired direction within an array’s steering angle limits. Adjustable attenuators used for tapering can also be considered as beamforming elements. This article discusses where and how a tiered approach between TTDs and PSs in the same ESA can be helpful to mitigate some phased array design challenges. Download the full paper to learn more.
