SPICE model for ATF36077 in ads

This is now Avago and not Agilent.

Look here:

(70mil Ceramic) Low Noise High Freq PHEMT 5 dBm P1dB

On Documents tab there is a link to a Spice Model

thanks.but How to add ATF36077 model to ADS library?

The file contains only the model parameter values, for small signal operation, so this is easiest just to use this data directly in any ADS schematic. The file is not in a format that can be imported or included without alteration.

Just place a Curtice2_Model element (from the Devices-GaAs palette/library) and fill in the parameters as provided. If a parameter value is not provided just leave it empty.

Then place a GaAsFET element from the same palette/library and refer it to that model.
