| 摘要: |
| DDS是一种数字波形合成技术，具有频率转换速度快、频率分辨率高、相位噪声低等优良性能，因此利用DDS作为可变参考源是比较理想的。本文采用DDS作为参考源驱动PLL频率合成器，实现了一个用于S波段遥测接收机的DDS/PLL频率合成器，同时对DDS/PLL频率合成器的输出特性进行了理论分析，并给出了实验结果。 |

| Abstract: |
| DDS is a kind of digital waveform synthesizing technology which has such good performance as short switch time, high frequency resolution and low phase noise. DDS is a good approach to be a reference of a frequency synthesizer. In this paper a DDS-driven-PLL frequency synthesizer for S-band telemetry receiver is described. The output characteristics of the DDS/PLL frequency synthesizer are also analyzed theoretically and the experiment result is presented. |
