摘要
对多频率干扰信号通过功率放大器时互调分量的产生进行了理论分析,提出了对互调分量的改善措施以避免其对试验结果造成影响,最后通过实验对分析结果进行了验证。
In this paper,the causes of intermodulation products generated by multi-tone radio frequency signal inputted into power amplifier are theoretically analyzed.The improvement approaches of the intermodulation products are proposed to avoid the influence on the test results.Finally,the results are experimentally verified.
