摘要
Provided is a receiver of a passive radio frequency identification (RFID) reader, which eliminates a leakage signal from a reception signal comprised of a RFID tag response signal and the leakage signal. The receiver includes a phase adjustment unit adjusting a local oscillation signal received from a frequency synthesizer to have a phase difference of a predetermined angle from the leakage signal. Since the phase adjustment unit adjusts the phase difference, the leakage signal input to the receiver of the RFID reader can be eliminated. Consequently, the performance of the receiver can be enhanced.
