Abstract

Achieving high performance, multifunctionality, and a compact size simultaneously in a single T/R module presents a significant challenge. In this work, both the 'chiplet' technique and 3D integration technique are adopted to form a T/R microsystem using self-matching interconnectors. Such T/R microsystem consists of four GaAs chips and one CMOS chip. The designed microsystem with a small size is utilized for the application of tile-type mmWave active phased array. Its measured results demonstrate good performance in terms of high gain, large output power, 6-bit phase shift, and 6-bit attenuation, confirming the effectiveness of our adopted architecture and design method. As such, this work provides a valuable design guideline for the chiplet-based 3D integrated RF microsystem.

带 0.5 波长自匹配连接器的晶圆级 3D 集成 T/R 微系统

在单个 T/R 模块中同时实现高性能、多功能和小尺寸是一项重大挑战。在这项工作中，采用了 "chiplet "技术和三维集成技术，利用自匹配互联器形成了一个 T/R 微型系统。这种 T/R 微系统由四个砷化镓芯片和一个 CMOS 芯片组成。所设计的微系统体积小，可用于瓦片型毫米波有源相控阵。测量结果表明，该系统在高增益、大输出功率、6 位相移和 6 位衰减方面性能良好，证实了我们所采用的架构和设计方法的有效性。因此，这项工作为基于芯片的三维集成射频微系统提供了宝贵的设计指南。
