摘要

本文研制了一种基于DDS和锁相环的x波段频率源，输出范围为11.75~12.25GHz。DDS可以通过FPGA和PC进行控制。根据快锁分析、低杂散分析和低相位噪声分析，通过MATLAB仿真选择最优环路参数。从而实现低相位噪声、频率捷变和低杂散。根据测试结果，最佳频率开关时间小于10us，相位噪声优于-104dBc/Hz@10kHz，杂散优于-50dBc，步长2.5kHz。

The design of high performance X-band frequency synthesizer based on DDS and PLL

In this paper, an X-band frequency source based on DDS and PLL whose output is 11.75~12.25GHz is developed. The DDS can be controlled through FPGA and PC. According to fast-locked analysis, low spurious analysis and low phase noise analysis, the optimal loop parameter is selected upon MATLAB simulation. Then low phase noise, frequency agile and low spurious are achieved. On the basis of the test results, the best frequency switching time is less than 10us, the phase-noise is better than -104dBc/Hz@10kHz, the spurious are better than -50dBc and step size 2.5kHz.
