ABSTRACT:
A frequency synthesizer and a method thereof. The method comprises grouping the carrier frequencies into first through fifth frequency groups comprising the first to third frequencies, the fourth to sixth frequencies, the seventh to ninth frequencies, the tenth to twelfth frequencies, and the thirteenth to fourteenth frequencies, generating a center frequency of the third frequency group, frequency mixing the center frequency of the third frequency group to produce center frequencies of the first, second, fourth, and fifth frequency groups, and performing frequency mixing on the center frequencies of the first through fifth frequency groups to produce two adjacent frequencies for each center frequency.
