【Abstract】 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.更多还原
