TOM_Model:Triquint Scalable Nonlinear GaAsFET Model

The PSpice Level 3 GASFET model is translated to the ADS TOM_Model. For translation information on the GaAsFET device, refer to Bxxxxxxx.

For more information on the ADS model, place the model in a schematic and choose Edit > Component > Edit Component Parameters to view the model parameters. You can also click Help in the component editor dialog box for additional information.
