A Ka-band phase-locked source (PLS) is analyzed and studied in detail. The stability of the millimeter 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 assembly technology are utilized in structure. Finally the millimeter PLS possesses features of miniaturization and low phase noise and high frequency stability.
