ABSTRACT:
A frequency synthesizer having reduced spurious components for use in a receiving and transmitting apparatus. The frequency synthesizer includes a direct digital synthesizer (DDS) for generating a first signal having a first frequency determined by channel setting data. The first signal is applied to a frequency divider to generate a divided signal having a divided frequency. The divided signal is applied to a frequency converter for shifting the divided frequency by a shift frequency interval to provide a reference signal having a reference frequency. The reference signal is applied to a phase locked loop (PLL) for generating a final signal having a predetermined frequency characteristic.
