本文提出了一种带片上天线的 110-140GHz 可重构雷达前端 IC。该 IC 包含两个可切换输入缓冲器、两个倍频器、一个 PA、一个 LNA、一个 SPDT HBT 开关和一个片上天线，完全集成在 SiGe 技术中。该雷达传感器适用于多基地雷达阵列，其中每个单元都可以配置为 Tx 或 Rx，比传统雷达阵列提供更多灵活性和信息。该芯片可以配置为发射器或接收器。封装 IC 的特点是具有或不具有介电透镜的 FMCW 雷达。该雷达可覆盖 110 至 140 GHz 的 30GHz 带宽，测量距离分辨率为 7.1 毫米。通过更大的增益变化，还可以将带宽扩展至 46GHz。
This paper presents a 110-140GHz reconfigurable radar frontend IC with on-chip antenna. The IC contains two switchable input buffers, two frequency multipliers, a PA, an LNA, a SPDT HBT switch and an on-chip antenna, fully integrated in a SiGe technology. The radar sensor is intended for a multistatic radar array where each unit can be configured as Tx or as Rx, providing more flexibility and information than conventional radar arrays. The chip can be configured either as transmitter or receiver. The packaged ICs have been characterized as an FMCW radar with and without dielectric lenses. The radar can cover a 30GHz bandwidth from 110 to 140 GHz, leading to a measured range resolution of 7.1 mm. An extend bandwidth of 46GHz is also possible with larger gain variation.
