摘要
利用幂级数法预测无源交调的幅度和功率的一般思路和方法 ,推导了由低阶无源交调测量值预测高阶交调 (特别是奇次交调 )幅度和功率的通用数学表达式 ,编程实现了用三阶无源交调的测量值预测五阶无源交调的功率 ,并与实验值进行了比较 .初步证实了这种方法的正确性和有效性 .
General ideas and methods of predicting the PIM amplitude and power level (especially odd order PIM) by using the power series are presented. A general mathematical formula is derived regarding the prediction of the higher-order PIM amplitude and power level with a lower-order counterpart. Prediction of the fifth order PIM power level with third order measured values is realized by a computer program. Calculated values are compared with experimental results, indicating that the developed theory is right and practical.
