DOI: 10.1109/tap.2019.2896733
Abstract: In this paper, a Ka-band digital beamforming array transmitter (DBFAT) using direct digital synthesizer (DDS) for millimeter-wave (mmW) applications is proposed. The system architecture, realization, generation, and measurement process of multiple beams are introduced. The… read more here.
