I am building a project home automation system, and trying to use PT2262/ PT2272 for coding and decording the data.

I need to modulate the signal from PT2262 with 'Surface acoustic wave' (SAW) resonators, and extract the signal and feed to 2272 for decording, as it seems a low cost solution and very useful in home automation.

I found some SAW resonators (eg 315Mhz) but could not find the details on how to integrate the SAW with the PT2262, and demodulate/ decode at the receive end.

Here is a link to the 315 Mhz (LR1 315.00) SAW:

I have noticed this combination is used in most industrial wireless atomation systems, and would be very useful to develop one.

Please help
