A wireless communication device and method

The radio communication apparatus and method is disclosed. A wireless communication device that drives on the basis of a predetermined driving voltage, transmitting and receiving unit transmitting and receiving a predetermined signal from the external device and the wireless communication, and demodulates the signals received from the data extraction unit transceiver extracts the data, and load modulation portion by the rectified voltage when a load modulation of the data to be transmitted to an external device, modulates the data so that the driving voltage less than the interior and transferred to the transceiver, the clock extraction section by using the comparator extracts clock signals from the transmitting and receiving the negative voltage change. In this way, being a modulation width is the maximum extension the read distance of the radio communication apparatus.
