Then presented the basic structure, phase model, frequency response and performance analysis for noise and spur, of phase locked loop (PLL).
然后介绍了锁相环(PLL)的基本结构、相位模型、频率响应、噪声及杂散性能。
2
Through comprehensive measurement of the frequency synthesizer, It shows that this synthesizer has good performance of the phase noise and spur restraint.
通过对频率合成器性能指标的测试，该频率合成器具有较好的相位噪声和杂散抑制性能。
3
Using the method and formula above, a L-band synthesizer has been finished. It has satisfactory performance on phase noise, frequency jump speed and spur rejection.
