摘要

提出了一种0.32太赫兹近程高分辨率雷达系统。它采用基于低成本SiGe HBT芯片组的同差FMCW雷达架构。它采用0.13 μm SiGe工程技术版本，截止频率fT /fmax为300/350 GHz，并提供镜头集成的片上天线。在0.311太赫兹下，封装发射机的最大辐射功率为-5 dBm (EIRP为14 dBm)。芯片组的6db工作带宽在0.325 THz中心频率附近为27 GHz。包括天线效率在内的接收机转换增益为-16 ~ -8 dB，在工作带宽上噪声系数为30 ~ 37 dB。FMCW雷达功能在面对面芯片组配置中进行了演示。

A 0.32 THz FMCW radar system based on low-cost lens-integrated SiGe HBT front-ends

This paper presents a 0.32 THz high-resolution radar system for short-range applications. It utilizes a homodyne FMCW radar architecture based on a low-cost SiGe HBT chip-set. It is implemented in a 0.13-μm SiGe engineering technology version with cutoff frequencies fT /fmax of 300/350 GHz and offers lens-integrated on-chip antennas. The measured maximum radiated power of the packaged transmitter is -5 dBm (14 dBm EIRP) at 0.311 THz. The 6-dB operational bandwidth of the chip-set is 27 GHz around the center frequency of 0.325 THz. The conversion gain of the receiver including antenna efficiency is -16 to -8 dB and its noise figure is 30-37 dB over the operational bandwidth. The FMCW radar functionality is demonstrated in a face-to-face chip-set configuration.
