Abstract
This paper presents a 28-GHz CMOS four-element
phased-array transceiver chip for the fifth-generation mobile
network (5G) new radio (NR). The proposed transceiver is
based on the local-oscillator (LO) phase-shifting architecture,
and it achieves quasi-continuous phase tuning with less than
0.2-dB radio frequency (RF) gain variation and 0 .3
◦ phase error.
Accurate beam control with suppressed sidelobe level during
beam steering could be supported by this work. At 28 GHz,
a single-element transmit
