upconversion mixer simulation spectrerf

Dear all,

I am doing dual up conversion mixer simulation using SpectreRF simulator. However, I do not know the setting of NF and voltage gain simulation. I hope you could give me a step for reference. My simulation input is as follow:

RF input: DC with a band from 0 ~ 250MHz (the RF input signal is DC and up converted to the required frequency range)

LO1: 1.3GHz

LO2: 2.1GHz

The upconverted frequency is 3.4GHz

At the same time, I attached the schematic of the two up conversion mixers connection and source generation. I use two ports and VCVS to generate the quadrature output for RF and LO1. How could I select in the pnoise (Input Source) and the pxf selection in order to get a correct result?

Thanks

Oh! Could anyone help me?
thanks
