how to plot noise circle in hb+hbnoise simulation?

Hi folks, 

I want to plot noise circle with hb + hbnoise simulation, but struggling to set-up the simulation bench. 

my test bench is RF receiver including de-modulation with fRF /fLO / fIF.

1) A port-adapter is placed after input port and fRF is set. I want to find Zopt to minimize NF based on noise circle plot.

  

2) hb and hbnoise are set-up as above. my concern is that frequency in hb set-up(fLO) is not equal to frequency in port-adapter(fRF).

it'd be really great if someone can help me set-up this simulation correctly.
