# What does an ideal phase response look like for a single port SAW resonator?

I've been struggling to find an example of an ideal phase response for a single port SAW resonator. In particular, I'm looking for a graph similar to this one:

which shows the admittance/conductance and phase response of a BAW resonator, but for a SAW resonator. Can I expect the same type of response out of a SAW resonator as that shown in the graph above, or will it be different? Forgive me if this is a basic question, I have a textbook on SAW devices in front of me but can't for the life of me find anything about the phase response in it (or in my extensive Google searches for that matter). Any help would be greatly appreciated!

• Thanks @glen_geek, this helps. To help any others looking at this question I also went back to fundamentals, remembering that purely capacitive reactance results in a voltage that lags current by $\frac{\pi}{2}$ while purely inductive reactance results in a voltage that leads current by $\frac{\pi}{2}$. This explains the relationship between the reactance in the graph shown above for the BAW resonator and the phase, and would similarly apply for a SAW resonator. Dec 9 '16 at 14:44
