摘要：

This paper presents a design plan for the frequency synthesizer base on DDS and PLL of the digital receiver, the main hardware selection is shown. Finally through the system test, the results show that the frequency accuracy of the frequency synthesizer reaches 3.72x10(-8), the resolution is 1Hz, the phase noise is 103dBc/Hz@l kHz the clutter rejection is 67dB and the frequency conversion time reaches 9.6ms. This frequency synthesizer can produce low phase noise, high resolution and high stability of the broadband signal. It has excellent technical performance, has been widely used in engineering.
