Abstract :
A kind of passive RF identification system is discussed in the paper. The system adopts a pair of passive dispersive SAW filters for pulse expansion and compression. And the principle of transmitter is introduced in detail. The asking pulse utilizes LFM theory to be expanded and the experimental results are demonstrated finally. The results show that the transmitter based on SAW can emit ideal asking pulse having pure spectrum and can be identified by SAW tag of receiver correctly.
