| 摘 要： | 该设计通过谐波混频的方式实现常规分频式锁相环所难以实现的低相噪指标。在理论分析的基础之上,提出微波低相噪锁相环设计方案,制定实际电路结构,通过对电路的调试达到在5.5GHz频点输出-111.30dBc/Hz@10kHz的相噪指标和-67.33dBc的杂散指标。验证了通过谐波混频的方式实现微波低相噪锁相的可行性。

| Abstract: | The purpose of research is to obtain lowphase noise in the Phase locked loops by means of harmonic mixer,which is impossible with the method of traditional PLLS.On the basis of theory analysis,we introduces the design project design of low phase noise microwave phase-locked source and make the circuit structure to identify this theory.After adjusted,the circuit reach to a ideal result.phase noise is-111.30 dBc/Hz@10KHz and Spur compression is-67.30 dB at the 5.5 GHz frequency point. |
