Abstract
An RFID reader is operable to receive an inbound RF signal during transmission of an outbound RF signal. The inbound RF signal may be a modulated, backscattered signal from a tag that has substantially the same frequency as the outbound RF signal or at a different frequency from the outbound RF signal. The receiver section of the RFID reader is operable to down convert the inbound RF signal by using a transmitter signal generated by the transmitter section to generate at least one local oscillation signal. The receiver section then processes and digitizes the down converted inbound RF signal to produce an encoded inbound signal.
