| Abstract: | 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. |
