高数据速率无线链路是替代或补充光纤的经济实惠且易于部署的解决方案。在100 GHz以上的毫米波上可用的宽频带可以支持每秒数千兆位的数据速率。然而，由于雨水和湿度造成的高衰减对长距离链路构成了重大障碍。这项研究描述了一种正在开发的用于D波段（DLINK）点对点链路的无线系统，频率高于150 GHz，以实现超过1 km范围的全光纤空中链路和高达45 Gb/s的前所未有的数据速率。D波段频谱的上端（151.5-174.8 GHz）用于全频分双工传输。DLINK系统包括一个发射机，使用直接调制的共振隧穿二极管振荡器由新型行波管供电。前端的性能和小尺寸将使DLINK系统与目前市场上频率低于100 GHz的点对点链路相比具有很强的竞争力。创新的方法和设计面向大规模生产，以满足新的5G基础设施的高数据流量需求。
High data rate wireless links are an affordable and easily deployable solution to replace or complement fibre. The wide frequency band available at millimetre waves above 100 GHz can support multi‐gigabit per second data rate. However, the high attenuation due to rain and humidity poses a substantial obstacle to long‐range links. This study describes a wireless system being developed for point‐to‐point links at D‐band (DLINK), above 150 GHz, to enable a full fibre‐on‐air link with more than 1 km range and unprecedented data rate up to 45 Gb/s. The upper end of the D‐band spectrum is used (151.5–174.8 GHz) in full frequency division duplex transmission. The DLINK system consists of a transmitter using a directly modulated resonant tunnelling diode oscillator powered by novel travelling wave tubes. The performance and the small footprint of the front end will make the DLINK system highly competitive to the point‐to‐point links presently available in the market at frequencies below 100 GHz. The innovative approach and the design are oriented to large‐scale productions to satisfy the high data traffic demand of the new 5G infrastructure.
