Simulation of two re-combined signal out of phase w/mixer

In system simulation, I can properly simulate the cancellation of two CW signal path which are known to have 180 degree phase difference by ploting the output specrum amplitude.  Unfortunalty, when there is a mixer in one of those two signal path, the siulation doesn't work anymore.  Do you have a model for system model for mixer which deal properly with the phase information or do you have a frequency translating device that can be used with the linear simulation?
