Question on using Ansoft Designer to analyze the bjt's small signal s-paramter with the nonlinear model

When using Ansoft Designer to analyze the bjt's small signal s-paramter with the nonlinear model(using linear network analysis ),I found the resulted s-paramters are different far from with the s-paramters provided by vendors.
Can anyone show me where is wrong?
Thanks!

The schematic and result are as attachment:

Make sure you are simulating under the same conditions (power range, bias etc.) and using the same model as the manufacturer. You will find differences between manufacturers models.
