摘　　要：本文设计并实现了用于相位噪声测量可数字调频的参考源。分析了锁相频率合成相位噪声的影响因素及锁相环调频的理论依据,给出了参考源合成方案。实验测试结果:频率覆盖范围3~6GHz,3GHz时10k Hz频偏处的相位噪声约为-131d Bc/Hz,6GHz时10k Hz频偏处的相位噪声约为-126d Bc/Hz,最大调频频偏100k Hz,具有较高的工程实用价值。The issue aims at the Study and realization of digital FM reference source for phase noise measure. Analyzes the factor of affect the phase noise of PLL frequency synthesizer, and the theory about PLL FM, introduces schematic design of frequency synthesize, The experimental results： The frequency range is 3-6GHz, Tile phase noise level is -131dBc/Hz@10kHz with output frequency of 3 GHz; The phase noise level is - 126dBc/Hz@10kHz with output frequency of 6 GHz, The maximum offset of FM is 100kHz. It has a high engineering practical value.
