| 摘 要： | 杂散抑制差和输出频率低是DDS的两大缺点,并且随着输出带宽的增加杂散性能更加恶化。传统的解决方法是采用更好的算法和改进DDS芯片本身的结构。该文在分析了DDS杂散性能和输出带宽相互制约的DDS阵列方法基础上,尝试了一种新的解决办法棗DDS阵列方法。同时还分析了这种方法的性能,并通过实验验证了其可行性。

| Abstract: | Spectral purity and frequency capacity are performance barriers of Direct Digital Frequency Synthesizers (DDS) that designers are striving to break. Traditionally, spurious signals are reduced by ways of better algorithms and improvements on DDS structure. In this paper a novel spur reduction method, DDS array method, is proposed and its performance is analyzed. And an experiment on the technology is operated to verify its feasibility. |

| Keywords: | frequency synthesis DDS array spur reduction bandwidth |
