Both the indirect contributions of the second-order Taylor series coefficients to the third-order intermodulation products and the contributions of the cross-terms to overall intermodulation products are included. 在此模型中考虑了二阶泰勒级数系数对三阶互调失真及交叉项对整个互调失真的影响。
Overall, this thesis from the passive intermodulation generation mechanism, combined with knowledge of microwave and digital circuit, the design and development of the RF components through of mobile communication frequent-band passive intermodulation measurement system. 总之,本文从无源互调产生机理出发,结合微波和数字电路知识,设计开发了移动通信频段无源互调测试系统的射频组件。
