This paper will introduce the design of wideband frequency agility synthesizer based on method of Simulate direct frequency synthesis, the full-phase coherence Modulation and Filter bandwidth control are applied in this synthesizer as designed .The main factors and solutions of the effect of the frequency switching time are analyzed and the frequency change time of the system is tested.The result shows that the frequency switching time between any two frequencies is less than 0.8 μs on the full band.
