Does anyone can provide the SPICE model of switch ADG902?
Unfortunately, the ADG902 Spice Model is not available as of the moment. On the other hand, you may use the evaluation board if you wish to evaluate the performance of the ADG902.

Let me know if this helps.
s2p files demonstrating the RF performance of the ADG902 can be found on the ADG902 product page. Below is the link for ADG902 product page. Please download the s2p file for there.
