The attached S-Parameters are recorded in differential to single ended configuration with the device at 25 degrees Celsius, and a 5V single supply. 

The measurement was performed with RF probes landed on 2.3mm long 50 ohm grounded coplanar waveguide line lengths leading to the device. These features are not de-embedded from the measurement.

Porting is as shown in the comments section in the .s3p file.
