本文报道了一条0.666太赫兹(666 GHz)数据链路的演示。在测量湿度为18%,接收机输出信噪比大于40dBSNR的情况下,采用QPSK调制,在590 m的范围内,峰值无差错数据速率为9.5 Gbps。0.666太赫兹链路使用InP HEMT变频器,提供低噪声和功率放大、行波管放大器和先进的调制解调器架构。这一地面演示表明,传统的通信方法可以很好地应用于亚毫米波范围。此外,基于这种技术的天基交叉链路应该能够在LEO-LEO范围内传输Gbps级的数据速率。
This paper reports demonstration of a 0.666 THz (666 GHz) datalink. A peak error-free data rate of 9.5 Gbps is demonstrated over a 590 m range using QPSK modulation with a measured humidity of 18% with more than 40 dB SNR at the output of the receiver. The 0.666 THz link uses InP HEMT frequency converters providing both low noise and power amplification, a traveling wave tube Amplifier, and an advanced modem architecture. This ground-based demonstration indicates that traditional communications approaches can be used well into the submillimeter wave range. Moreover, a space-based crosslink based on this technology should be capable of transmitting Gbps-class data rates at LEO-LEO ranges.
