Honglei Zhou · Guidance and Fuze · 2011
Introduces the realization scheme and key technology of S band PLL+DDS swept frequency synthesizer.Glancing adjusting the PLL and nice adjusting the DDS design approach is used to realize small step-size,high spectrum purity and low phase noise.The specifications shows that the swept frequency synthesizer can realize continuous signal,LFM and agile signal with high spectrum purity and low phase noise.
