ABSTRACT:
A wireless communication device including: a transmitter including two DA converter units which convert two digital signals into analog signals; a combiner which combines the analog signals; a distributor which extracts a portion of the combined signal as a feedback signal; an AD converter which converts the feedback signal; an oscillator unit which supplies clock signals to operate the DA converter units and the AD converter; a first separation unit which separates the feedback signal converted by the AD converter into two signals; and a comparator unit which compares at least one of the two digital signals that are obtained by separating the inputted digital signal, or, at least one of the two digital signals that are separately inputted, with the feedback signal separated by the first separation unit, wherein the oscillator unit controls the output clock signals based on a result of the comparison by the comparator unit.
