FH(Frequency-Hopping) communication is a very important method of anti-jamming.The FH frequency synthesizer is one of the kernel component that is used to realize FH communication.The low phase noise and fast frequency switch lock time are the most important target of FH frequency synthesizer.This paper summarizes the analytical method and simulation results in our design process about wide band FH synthesizer.Using DDS chip of AD9956 which is based on the DDS/PLL technology to fabricate a wide band FH synthesizer in S band and realize the performance of wide band,low phase noise and fast lock.
