液氮环境下的热载流子高功率微波探测器
High power microwave hot-carriers detector in liquid nitrogen
摘要
Abstract
In order to enhance the sensitivity of high power microwave detector and reduce the impact of ambient tempera-ture,research of hot-carriers detector in liquid nitrogen was carried out.Kovar alloy was used in the BJ-100 waveguide HPM de-tector to enhance the ability of resisting temperature change.The binding force is bigger than 4.9 N in the test.Sensitivity experi-ments of the HPM detector at room temperature and in liquid nitrogen were conducted using the microwave source.Waveform of the HPM detector is consistent with that of the Schottky detector.The relative sensitivity of the HPM detector in liquid nitrogen is 20 times higher than that in the room temperature under the constant current,and the output voltage amplitude can be above 1 V.关键词
