摘　　要：本文对Ka波段锁相源作了分析和研究,探讨了毫米波锁相环路的稳定性和相位超前补偿问题。采用双锁相环路研制了腔稳偏压调压控振荡器(VCO)、高次倍频器、低相噪微波锁相源等关键部件,采用了表面安装技术(SMT)和高密度组装技术,使研制的毫米波锁相源具有小型化、低相位噪声、高稳定度等特点。A Ka-band phase-locked source (PLS) is analyzed and studied in detail. The stability of the millimeter wave PLL and the theory of phase compensation are discussed. In the practical scheme, the double PLL is applied, and the key components, such as the stable-cavity bias-tuned VCO, high-order multiplier and low phase-noise microwave PLL are developed. The SMT and high density assembly technology are utilized in structure. Finally the millimeter wave PLS possesses features of miniaturization and low phase noise and high frequency stability.
