The Design of the RF Front-End of Reader Based on SAW RFID
This paper first describes the system architecture and operating principle of SAW Radio Frequency Identification Devices (RFID). Then it provides the designing scheme to the radio frequency front end of 915 MHz ultra high frequency (UHF) reader. At last, it lists the test method to the RF front end system, and system-level verification of RFID reader. The results show that, this design meets the performance index of 915 MHz reader, and has properties of reliability, efficiency and flexibility in configuration and maintenance.
