本文介绍了一种28 GHz 16单元相控阵接收器，该接收器采用28 nm体射频CMOS体工艺，面向5G NR应用。该接收器采用高增益低噪声低噪声放大器、带后失真的线性增强型射频放大器和RF/IF阶跃衰减器，可实现宽增益范围和精细的增益阶跃控制。因此，对于5G NR800/100 MHz信号，该接收机的系统噪声为3.5d B，增益控制范围为50d B(1d B步长)，均方根值为-37.7/-43.1d B，而功耗为0.54W(相当于每个通道33.5 mW)。
This paper presents a 28GHz 16-element phased-array receiver in a 28nm bulk RF CMOS process targeting 5G NR application. The receiver implements a high-gain low-NF LNA, a linearity enhanced RF amplifier with post-distortion, and RF/IF step attenuators for a wide gain range and fine gain step control. Thereby, the presented receiver demonstrated a system NF of 3.5dB, a gain control range of 50dB (1dB step), and an EVM of - 37.7/-43.1dB with 5G NR 800/100MHz signals while consuming a low power of 0.54W (equivalent to 33.5mW per channel).
