Research on terahertz radio frequency devices and integrated technologies

无线通信、探测感知、安全检测、人工智能等民用和国防电子信息技术的不断快速发展与演进,对太赫兹(0.1~1 THz)技术提出了越来越迫切的应用需求。太赫兹波段具有丰富的频谱带宽资源,其宽带特性可以支撑未来6G高速率通信、新一代高分辨雷达系统性能的实现。同时,太赫兹通信和探测必须克服高频率、短波长所带来的高传播路径衰减、激增的无源器件与互连损耗以及有源器件功率生成和效率难题。本文将回顾太赫兹射频器件与集成技术的发展现状,阐述上海交通大学团队通过新型无源、有源器件与天线及其先进封装等技术方法,整体提升太赫兹前端系统性能的相关研究进展。

The rapid development and evolution of civilian and defense electronic information technology,such as wireless communication,detection and sensing,security inspection,and artificial intelligence,have increasingly urgent application demands for terahertz(0.1~1 THz)technology.The terahertz band has rich spectrum bandwidth resources,and its broadband characteristics can support the implementation of future 6G high-speed communication and new generation high-resolution radar system performance.At the same time,terahertz communication and detection must overcome the high propagation path attenuation and surge of passive devices and interconnect losses,as well as the power generation and efficiency problems of active devices brought about by high frequency and short wavelength.In this paper,the development status of terahertz RF devices and integration technology are reviewed,and the research progress of the Shanghai Jiao Tong University team in overall improving the performance of terahertz front-end systems through new passive and active devices,antennas,advanced packaging,and other technical methods are elucidated.
