摘要

冰云探测对于提高天气预报准确性、监测极端天气现象等具有重要的意义.考虑到冰云粒子尺寸、形状分布等因素, 利用太赫兹频段被动遥感仪器能更好地解决冰云探测的难题.664 GHz作为一个重要的探测频点, 其接收机射频前端主要包括664 GHz二次谐波混频器、332 GHz二倍频器以及166 GHz大功率源.作者在太赫兹二倍频设计的基础上, 利用两路功率合成技术实现166 GHz大功率源, 目的是提供给后级的332 GHz二倍频器足够的输入功率, 从而能够驱动谐波混频器工作.实验结果表明, 上述大功率源在164~172 GHz频率范围内输出功率大于46 mW; 在168 GHz处有最大输出功率59 mW.以上研究有效解决了本振链路中G波段输出功率不足的问题, 为研制更高频段的太赫兹系统提供了技术支撑.

Abstract

Ice clouds measurement technology plays an important role in improving the accuracy of the weather forecast and monitoring extreme weather phenomena and so on. Considering the physical dimension and shape distribution of ice-cloud particles, the problem of ice-clouds detecting could be solved by using terahertz passive remote sensing instrument. As an important detecting channel, the 664 GHz RF front-end of receiver mainly includes a 664 GHz sub-harmonic mixer, a 332 GHz doubler and a 166 GHz high power source. Based on the design of terahertz doubler, a 166 GHz high power frequency multiplying source has been realized by using two way power-combined technologies. The measured results show that the output power of above-mentioned source is more than 46 mW in 164~172 GHz and the highest output power is 59 mW at 168 GHz. The above-mentioned research could solve the problem of lacking of the G band high power source in the LO chain, and provide technical support for the design of terahertz system working at higher frequency.
