| 摘 要： | 给出了一种基于DDS驱动PLL的频率综合器结构。该结构采用AD9854DDS芯片产生低频的参考信号,然后驱动锁相环和VCO产生X波段射频信号。实验和测量结果表明,该频率综合器具有较宽的工作带宽和较低的相位噪声,可以用来产生连续波、线性调频信号和频率捷变信号用于X波段雷达信号的仿真。 |

| Abstract: | 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 show that this frequency synthesizer has 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. |
| Keywords: | DDS phase locked loop radar signal frequency synthesizer |
