偏置功率匹配器在微波小功率校准系统8mm频段应用

摘要

In order to improve measurement accuracy of the microwave small power sensor In the 8mm wave band, The new microwave power calibration system based on low reflectance equivalent signal generator was made up through present system Ⅱ calibration system and bias power matcher. This paper recounted design and working principle of bias power matcher. The system has virtues on conveniences and stability and accuracy.%为了提高8mm微波小功率敏感器的校准准确度,利用原有的SYSTEMⅡ微波小功率标准系统,通过研制偏置功率匹配器,在8mm频段构建了新型波导小功率敏感器校准系统.本文详细叙述了偏置功率匹配器的设计及其工作原理,该系统具有操作方便、性能稳定等优点,可实现对8mm波导小功率敏感器的准确校准.
