How to simulate the noise figure of a two-stage receiver in ADS?

Would anyone tell me some suggestions about my design? I will upload my design files in projects style later, as I found the noise figure is different from APPCAD's results.
Any tutorials for the noise figure simulation in ADS? Thanks.

The attachment is in .rar style. My question is that why the noise figure is varying from 7dB to 30dB with different rf input level. As I know, the noise figure should be indepent from the input power level( of course within the linear range of the mixers). Would anyone tell me where I am wrong in the setup of the parameters? Thanks.
