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。
In order to improve the calibration accuracy of 8mm microwave low power sensor, a new waveguide low power sensor calibration system was constructed in the 8mm band by using the original SYSTEMⅡ microwave low power standard system. This paper describes in detail the design and working principle of a bias power matcher, which has the advantages of convenient operation and stable performance, and can accurately calibrate a small power sensor with 8mm waveguide.
