摘　　要：应用取样锁相技术对Ku波段低相噪锁相介质振荡器进行了研究,对取样锁相技术的工作原理和电路特性进行了分析,阐述了取样锁相环路的设计过程。对制成的实物进行了测试和调试,取得了预期的相位噪声指标。实验结果表明,该取样锁相源的频率为17 GHz,输出功率≥10 dBm,杂波抑制比≥70 dBc,相位噪声-103 dBc/Hz@1 kHz,-107 dBc/Hz@10 kHz,-110 dBc/Hz@100 kHz,-128 dBc/Hz@1 MHz。Ku-band low phase noise locking phase oscillator with dielectric resonator was developed using sampling phase-locked technology. The theory and its characteristics of sampling phase-locked loop were analyzed and the design process was described. The circuit was realized with ideal low phase noise, and it was tested and modulated, The results show that the output frequency of the sampling locking phase oscillator is 17 GHz, output power is≥ 10 dBm, spurious rejection ratio is ≥70 dBc, phase noise are - 103 dBc/Hz@ 1 kHz, - 107 dBc/Hz@ 10 kHz, - 110 dBc/Hz@ 100 kHz, - 128 dBc/Hz@ 1 MHz.
