摘要:
针对空间应用中微放电效应对微波器件的制约,设计了一种C波段高微放电功率容量的波导同轴转换器。基于从局部到整体的微放电敏感区域分析方法,对同轴接头和馈电体进行优化,提出了改进型后馈式波导同轴转换器。频率在3.0~5.4 GHz时,回波损耗大于15 dB,插入损耗低于0.3 dB。实验测试得到微放电功率阈值突破7 kW,与理论分析结果吻合。该波导同轴转换器结构简洁,微放电功率阈值高,有望在空间得到应用。微放电分析的方法对空间微波器件抑制微放电的设计有借鉴意义。
Abstract:
Aiming at restriction of micro-discharge effect on microwave devices in the space applications, we designed a waveguide coaxial converter with high micro-discharge power capacity in C band. In this paper, based on an analysis of the sensitive area of multipactor from local area to the whole region, an improved end-launch waveguide coaxial with high multipactor power threshold is presented based on the optimized coaxial joints and feeders. Its return loss is more than 15 dB and and insertion loss less than 0.3 dB between 3.0 GHz to 5.4 GHz, respectively. The multipactor power threshold breaks through 7 kW in experiments, which agrees to theoretical analysis. The proposed waveguide coaxial converter has a concise structure with high multipactor power threshold, which is prospective in future application in space. The analysis method may aid the design of microwave components in suppression of multipactor effects.
