Simulation model for SAW Resonator

saw resonator designs

Hello friends
I am looking for ADS simulation model for 315 MHz & 433.92 MHz SAW resonator.
(Temex or RFM or any vendor)
Can any one upload?

I want simulation model.
which I can place directly in simulation like transistors or resistors etc.
In PDF only there are specifications given.
But you need model to enter that specification.
There is one model in ADS but it has only two terminals. I dont know whether it will be correct to use.
the one that I require needs four terminals.
so I will ground two terminals & Use other two.
at this moment any model with the specified frequency will help.

You can ask the vendor to give S-para.
They do send you

This sounds like a SAW resonator based oscillator. The 2 port version, the traditional version, requires a phase shifter and a high gain transistor as the losses can be fairly high and in oscillators there is always mismatching as the transistor parameters change under large signal conditions. The 1 port design is more flexible and the recent SAW devices are described in a similar fashion as a quartzs crystal .Do not use devices with an Rs above 25 ohms
