In this paper, the design of a K-band phase-locked oscillator is presented. It uses sub-harmonic sampling phase-lock loop and push-push Dielectric Resonator Oscillator (DRO) of high quality factor to suppress its phase noise.

• 本文介绍了一种K波段频率源的设计方法,该频率源要求具有良好的相位噪声性能,因此采用分谐波锁相式振荡源,锁相环路中的压控振荡器采用推-推(push-push)式DRO,它可以更加有效的提高有源器件的工作频率,改善系统的噪声性能。
