pls specify the model for me explicitly.

The "SAW_Filter" (in the Filters-Bandpass libary), as khouly suggests, provides an electrical model for SAW devices. There is also a library of standard Sawtek filters under System Library > Filters.

It's also possible to define the frequency response of a SAW filter by writing s-parameter by hand at some critical frequencies.( as much as possible) then by using model composer of ADS, you may obtain a discrete lumped element equivalent of the filter.
Of course SAW filter will show a bandpass filter behaviour and to obtain a very accurate model is very tough.But it's worthy..

Normally, an industrial SAW filter has s-parameters,you can use them in model development..
