A 132-to-148GHz CMOS 4TX-4RX FMCW Radar Transceiver Array with Cavity-Backed Antenna-in-Package Achieving 28dBm EIRP

📋 论文概要

本文提出了一款132-148GHz CMOS 4TX-4RX FMCW雷达收发器阵列，采用腔体背衬天线封装技术，实现了28dBm等效全向辐射功率（EIRP），显著高于现有CMOS/SiGe D-band雷达收发器。该设计解决了D-band雷达因自由空间损耗大而需要高EIRP的问题。

💡 主要创新点

• 采用腔体背衬天线封装（Cavity-Backed Antenna-in-Package）技术，提升了天线效率和辐射功率。
• 在CMOS工艺上实现了4TX-4RX阵列架构，在132-148GHz频段内达到28dBm EIRP，远超此前报道的同类器件。

To compensate for the substantial free-space loss, D-band radar transceivers are required to generate a large equivalent isotropic radiated power (EIRP); however, the EIRPs of latest reported CMOS/SiGe D-band FMCW radar transceivers [4-8] were less than 11.6/18dBm without adopting lenses. ERIP is limited by three constraints: 1) array size of the reported single-chip FMCW radar transceivers [4-8] was only 1TX-1RX; 2) the low output power of the frequency multiplier and power amplifier (PA), which is due to the low breakdown voltage and unity-power-gain frequency (fMAX) of the advanced CMOS/SiGe process; 3) the
