Design and Improvement of a Frequency Synthesizer Based on PLL+DDS+PLL

摘要：

　　A L-band high performance frequency synthesizer is presented for space TT&C channel.PLL+DDS+PLL structure is used to realize small step-size,high spectrum purity and low phase noise.Experimental result shows that its phase noise is better than-100dBc/Hz@10KHz and its spurious suppression is better than-75dBc.But the additive spurious results co-frequency interference.Find out the case of cofrequency interference and propose corresponding countermeasures by analysis.
