Abstract :
A kind of passive RF identification system was discussed. The system used SAW as identification tag and works at ISM-915MHz. In order to improve anti-jamming performance and degrade the severe requirement for sensitivity of wide-band receiver, the system adopted a pair of passive dispersive SAW filters for pulse expansion and compression. Then, the structure of SAW tag, the principle of transmitter & receiver and DSP sub-system were developed respectively. Finally, testing results were demonstrated
