I am looking to use AD8302 as a phase detector circuit. What software would I use to build and simulate the AD8302 in measurement mode (fig. 4 from datasheet)? The simulation file associated with the product is a .s1p and I am unfamiliar with that file type.
The S1P file is RF s-parameters, a measure of the RF input matching and reflection coefficients.

If you're more interested in a behavioral model, sorry but I'm not aware of any models provided by Analog Devices. You could, however, consider writing your own model, as we sometimes do from time to time. The AD8302 datasheet talks about the phase detector internal architecture. See the bottom of page 15.
