摘要
本文讨论了微波单栅FET的等效电路模型、本振大信号分析的谐波平衡法以及RF小信号分析的多频变换矩阵法。建立了一套完整的FET混频器的分析设计方法。试验设计表明,本方法是简便而有效的。
The equivalent circuit model of microwave SGFET, the large signal analysis of LO injection by harmonic blance method and the small signal analysis of RF injection by multi-frequency conversion matrix method are discussed. A complete method for analysing and designing mixers in presented. The measurement results show that this method is simple and effective.
