A DDS-driven PLL frequency synthesizer architecture is given in this paper. The AD9854 DDS device is used to generate low frequency reference signal and to drive the PLL and VCO to generate RF signal. Experiments and measurement results showed that this frequency synthesizer had wider bandwidth and low phase noise level, and can be used to generate X-band continuous wave signal, FM chirp signal and frequency agile signal for radar signal simulation.
