Patent ID: 8861641

Claim:
A wireless communication device comprising: a mixer configured to multiply quadrature-modulated transmission data by a local oscillation frequency signal and output a high-frequency signal; a distributor configured to distribute the high-frequency signal; a detector circuit configured to detect a high-frequency direct current component included in the high-frequency signal, based on the high-frequency signal distributed by the distributor; a correction circuit configured to generate a correction signal for removing the high frequency direct current component from the high-frequency signal, based on the high frequency direct current component detected by the detector circuit; an adder configured to correct the high-frequency signal by the correction signal generated by the correction circuit; a controller configured to determine whether the quadrature-modulated transmission data includes a direct current component; and a transmission unit that transmits the high-frequency signal that has been corrected by the adder, wherein, when the controller determines that the quadrature-modulated transmission data does not include the direct current component, the controller causes the adder to correct the high-frequency signal by the correction signal generated by the correction circuit.
