How to plot NF vs RF Frequency in cadence

[john.zhang]

Hi,

I am designing a down conversion mixer which takes in an input RF freq of 70 to 80Ghz, however when I try to plot the NF, it's only possible to get NF vs output frequency plot, will it be possible to get the NF vs RF Freq plot?

thanks

It's same thing.Mixer Noise will be appeared at the Output so there is no difference between NF versus Input/Output Frequency since IF is fixed.
If you would like to see NF versus Input Frequency, add or subtract IF..
