In this paper, we present and demonstrate a novel approach of a true time-delay (TTD) optical feeder for phased-array antennas (PAAs). A continuously variable TTD is achieved by employing tunable ...

This paper presents a 28-GHz 16-element phased-array transmitter for the fifth-generation (5G) new radio (NR) applications, focusing on the power amplifier (PA). The IC was fabricated using a 28-nm ...
