Abstract: 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. -
