Claim:
1. A wireless communication device comprising: an analog control loop circuitry that generates an analog control signal to adjust a phase of a voltage controlled oscillation signal, in accordance with a phase of a reception signal; a digital control loop circuitry that generates a digital control signal having a frequency determined by a frequency of a reference signal and a predetermined frequency setting code signal and having a phase opposite to a phase of the analog control signal; a voltage controlled oscillator that generates the voltage controlled oscillation signal, on the basis of the analog control signal and the digital control signal; and a data slicer that generates a digital signal obtained by digital demodulation of the reception signal, on the basis of a comparison result of the digital control signal and a predetermined threshold value, wherein gain of the digital control loop circuitry is higher than gain of the analog control loop circuitry.
