Design of Frequency Hopping Synthesizer in Frequency Hopping Transceiver
Hongguang Ma · Modern Electronics Technique · 2009
Frequency Hopping(FH) synthesizer is the core of FH transceiver and also a difficulty for the design.In the paper,a project of fast FH synthesizer realized with DDS and PLL is brought forward,and the hardware design is completed.Its performance is estimated,and the results show that the blue print meets the requirements of the system design.The advantages of DDS and PLL are combined to realize high speed FH when designing,the shortcomings for the DDS,which can not outputs higher frequency,and the PLL,whose locking time is longer are abandoned.
