Abstract

To meet the growing need for higher data rates with improved energy efficiencies, this article demonstrates the application of resonant tunneling diodes (RTDs) for wireless communications at a frequency of approximately 860 GHz. By incorporating a low-loss air-bridge transmission line to form a cavity resonator and a ring-slot antenna, a two-RTD oscillator realized coherent terahertz radiation with a power output of 0.23 mW and a dc-to-RF efficiency of 0.2%. Experimental validation confirmed wireless data transmission for data rates up to 1.2 Gbit/s using on-off keying modulation with bit error rates below 10⁻⁹. To the best of our knowledge, this is the first reported demonstration of all-electronic oscillators for wireless communication beyond 850 GHz, paving the way for next-generation networks and advanced integrated circuits in the artificial intelligence-driven era.

860ghz谐振隧道二极管发射机和接收机的无线通信

为了满足日益增长的对更高数据速率和提高能源效率的需求，本文演示了谐振隧道二极管（rtd）在频率约为860 GHz的无线通信中的应用。通过采用低损耗气桥传输线构成腔腔谐振器和环槽天线，双rtd振荡器实现了相干太赫兹辐射，输出功率为0.23 mW， dc- rf效率为0.2%。实验验证证实，采用开关键控调制，误码率低于10−9，数据传输速率可达1.2 Gbit/s。据我们所知，这是首次报道的用于850 GHz以上无线通信的全电子振荡器的演示，为人工智能驱动时代的下一代网络和先进集成电路铺平了道路。
