大功率短波发射机常见滤波网络的测试调整

Test and Adjustment of Common Filtering Networks for High Power Short Wave Transmitter

大功率短波发射机由于其元器件尺寸较大,在测量、分析其工作于高频段的情形时,不宜作为集总参数电路进行分析,而是使用分布参数电路的分析方法进行处理,通过对分布参数电路中S参数的介绍,举例说明了大功率短波发射机常见二端口滤波网络的分析及测量调整方法。

When measuring and analyzing high-power short-wave transmitter with large components in high frequency band,it is not suitable to analyze as lumped parameter circuit,but to use the analysis method of distributed parameter circuit to process.According to introducing S parameter,this paper demonstrates that the analysis and measurement adjustment methods of common two-part filter network for high-power short-wave transmitter.
