In this paper a design of wideband direct synthesizer with full-phase coherence based on method of Simulate frequency synthesis is introduced.It adopts full-phase-coherence modulation,channelized design,filter band control technology and so on,and designs the system circuit,then analyzes the main factor and resolution method which influences the system capability.In the end the system capability is tested and the result indicates that the system achieves wideband-small-step output,its phase noise and clutter level is controlled in low level in full frequency band.
