.s2p files are the S-parameter measurements for the device. The vendor can supply them and there are many built into the @DS library. You access them in the schematic by using the S paramter DATA ELEMENT block and then within the block, point to the path of the file. The s2p files are usually stored in the data directory underneath your prj folder.
