<P>PROBLEM TO BE SOLVED: To provide an RFID reader which is made compact and whose power consumption is minimized by simplifying the structure of a transmission and reception section, and also improved in performance. <P>SOLUTION: Provided is the RFID reader reading data from an RFID tag using a wireless connection over a specified frequency bandwidth, including a transmitting unit synthesizing sequentially and cumulatively frequency control signals generated every clock, mixing the synthesized specific frequency signal and a fixed frequency signal, and as a result outputting an RF signal. <P>COPYRIGHT: (C)2007,JPO&INPIT |
