Description
Summary:This paper presents a 28-GHz four-channel phased-array receiver in 120-nm SiGe BiCMOS technology for 5G cellular application. The phased-array receiver employs scalar-only weighting functions within each front-end and then global quadrature power combining to realize beamforming. Differential LNAs and dual-vector variable-gain amplifiers are used to realize each front-end with compact area. Each front-end achieves 5.1 to 7 dB noise figure, -16.8 to -13.8 dBm input compression point, -10.5 to -8.9 dBm input third-order intercept point across 4-bit phase settings and a 3-dB bandwidth of 26.5 to 33.9GHz, while consuming 136 mW per element. RMS gain and phase errors are
