SAW based transmitter design

antenna for saw based transmitter

Hi All,

do you have any idea how does the SAW based transmitter really works with following criteria below:
0. center frequency tuning
1. data rate setup
2. antenna tuning
3. impedance matching

Any recommended design notes or information websites is appreciated?
Anybody Please help! Thanks

-Central frequency tuning is dictated by the SAW and by the components of the oscillator.
-The oscillator's transient time dictates the modulation rate.
-Impedance matching and antenna tuning is made in the way to achieve maximum RF power transfer from the transmitter to the free-space. Matching is done using a few components that helps in the same time to minimize the harmonics.
