摘　　要：对取样锁相频率合成器的工作原理、技术特点等进行了描述,着重分析了其低相噪、低杂散特性,讨论了环路滤波器与环路扩捕的设计对环路稳定性的贡献,最后给出了X频段取样锁相频率合成器的电技指标。The operation principle and technical features of a sampling phase -locked synthesizes are described in this paper. The low phase -noise and spurious features are especially analyzed, and the contribution of loop filter and loop capturing to stabilization of loop is emphasized. Finally the typical specification and performance of the X - band sampling phase - looked synthesizer is provided.
