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

Micky

saw transmitter design

RF Monolithics is one of largest manufacturers of SAW filters and resonators and has application notes and design information in its web site. Please try:

and you will find most of the information you require.

-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.
