GaN transistor

Hi,

I have a component "EPC2016C - Enhancement Mode Power Transistor" which is a Gallium Nitride FET. The "GaN RF/MW components" model mentioned in FIDES Guide 2022 seems suitable to use for this component.

However, this model is not available in de Fides template. Is there a way I can enter each PI-factor or final component lambda results from a hand calculation based on FIDES Guide 2022 into the Fides template? If not, what component and model would you recommend to select to get a fair result.

Kind regards,
Sara
