摘　　要：在对毫米波数字锁相环路进行分析的基础上给出了三阶环的工作参数，并设计了一个８ｍｍＧｕｎｎ振荡器数字锁相环路．实验结果表明，该环路锁定容易，而且频谱较纯．The working parameters of a third-order loop are deduced based on the analysis of a millimeter band digital phase-locked loop. A digital phase-locked 8 mm Gunn oscillator with a heterodyne-loop structure is designed. It is shown by the measurements that the performance of this loop is quite satisfactory. It has the characteristics of being easily locked and having a pure spectrum.

关 键 词：数字锁相环 极高频 鉴相器
