S波段快速低相噪宽带频率合成器的设计

Design of Wideband and Agile Synthesizer for S-Band with Low Phase Noise

在分析常规数字锁相环路噪声特性的基础上，提出了一种实用S波段快速低相噪宽带频率合成器方案，并进行了详细的相位噪声理论分析。研制样机的指标测试结果也验证了理论分析的正确性。

Based on the analysis of noise characteristic in general digital phase locked loop,one practical scheme of wideband and agile synthesizer for S-band with low phase noise is presented in this paper,and the phase noise of this synthesizer is analysed in detail. The validity of the theoretical analysis is also proved by the manufactured sample.
