Abstract
High-resolution mm-wave array beamformers have
applications in medical imaging, gesture recognition, and navi-
gation. A scalable array architecture for 3D imaging is proposed
in which single-element phase coherent transceiver (TRX) chips,
with programmable TX pulse delay capability, are mounted on
a common board to realize the array. This paper presents the
design of the enabling TRX ch ip: a highly integrated 94 GHz
phase-coherent pulsed-radar with on-chip antennas. The TRX
achieves 10 GHz of
