多功能微波功率检测模块设计

对于大多数射频微波系统,微波功率都是一个必不可少的评价指标.对于中小型的微波功率源系统,为满足系统的可测试性,往往需要增加对输出功率的量化检测,但使用仪表功率计则价格昂贵.详细介绍了一种简单、实用、经济性好的微波功率检测模块设计方法.该方法使用线性检波、采样保持、数据采集及软件校准等方法,实现了较高精度的峰值功率、调制脉冲功率信号脉冲重频及脉宽的检测,并通过试验将测试数据与功率计及示波器实际测量对比,验证了使用该方法研制模块测试精度.

Design ofmultifunctional power microwave power dectection module

For most RF microwave systems, microwave power is an essential evaluation index. For small and medium microwave power source systems, in order to meet the testability of the system, it is necessary to increase the quantitative detection of the output power. In this paper, a simple, practical and economical design method of microwave power detection module is introduced in detail. The method realized the detection of the high precision peak power, pulse repetition frequency and pules width by linear detection, sample hold, data sampling and software calibration methods. The test data are compared with the actual measurement of power meter and oscilloscope, and the measurement precision of the module developed by this method is verified.
