The method of rapid design applies ADS(Advanced Design System 2009) software to get the optimized parameters based on the ADI simulation tool ADIsimPLL is presented.It is used to achieve the rapid design of high performance,in line with the actual engineering of PLL Frequency Synthesizer.The PLL frequency synthesizer with the output frequency of 930-960MHz designed by the above method is also presented.The result show that the lock time,phase noise and phase margin of the frequency synthesizer have reached the goals.
