New type of high power microwave detector

摘要: 通过对半导体材料中载流子迁移率的特性分析，在原HPM探测器的基础上，提出了探测器中半导体传感器的新设计，使探测器的检测灵敏度提高一个量级；同时研制成功S波段HPM探测器。在传感器的加工方面采用了新的工艺，并对电源进行了改进，使之功能完善、使用简单、具有实用性。其电源偏压在40V时，X波段的探测器在60kW时输出检测脉冲信号幅度高达9V，S波段的探测器在600kW时输出检测脉冲信号幅度高达10V，可适用于10～500ns脉宽的HPM功率测量。Abstract: A new type detector was presented in this paper, which was developed based on novel sensors and new measuring circuits to achieve good sensitivity and reliability for HPM power measurement. Com pared with the previously developed X-band HPM detector, the new X-band detect or is characterized by 10 times higher sensitivity and over 9V output signal voltage amplitude at HPM power of 60kW. An S-band HPM detector was developed successfully for the first time. Both detectors can be used for power measuring of HP M whose pulse duration ranges from 10ns to 500ns.
