This paper applies a conversion matrix approach to the linearity analysis of a varactor-based 36-GHz CMOS parametric upconverter. The nonlinear model of the upconverter is explained and derived. The comparison between the measurements, simulations, and theoretical calculation is presented to show excellent agreements: 0.5- and 1.5-dB differences in conversion gains for lower-sideband and upper-sideband upconversion, and less than 2.9-dB in both IIP2 and IIP3 when converting a 1-GHz signal to 36-GHz output.
