Exporting an ADS EEHEMT1 model to Microwave Office

Dear all,

I noted down the EEHEMT1 model parameters used in ADS schematic, and then entered the parameters in AWR MWO,
reault is that transistor's S parameter, node voltages , drain current are right, but the gate current is wrong.

I notice that there is "Lshunt" parameter in AWR MWO whereas doesn't exist in ADS, and some parameter like "gmmax" unit is "H" not "S" in ADS,

Thank you in advance for your help
