There is provided a radio communication device including (a) a radio-receiving circuit which receives a radio signal, and transmits a receipt signal in accordance with the received radio signal, (b) a clock-generating circuit which generates a data-receiving clock, (c) a data-receiving circuit which receives the receipt signal in accordance with the data-receiving clock, (d) a phase-difference detecting circuit which detects a difference in a phase between the receipt signal and the data-receiving clock, (e) a phase-difference correcting circuit which varies a correction for a phase of the data-receiving clock in accordance with the difference in a phase detected by the phase-difference detecting circuit, and (f) a maximum correction establishing circuit which establishes a maximum correction for a phase of the data-receiving clock. In accordance with the radio communication device, when a data-receiving clock follows a radio signal in a phase, a correction for a phase of the data-receiving clock is varied in accordance with a difference in a phase between a received radio signal and the data-receiving clock, and a maximum correction for a phase of the data-receiving clock is also varied, which ensures higher accuracy with which a radio signal is received. As a result, it is possible to accomplish phase follow-up or synchronized receipt at an enhanced rate and with higher accuracy.
