Design of LFM Signal Source Based on AD9852
Wei Cheng · Hangkong bingqi · 2011
X-band LFM signal source is widely applied in many areas.On the basis of DDS-driven PLL,this paper makes up for the shortcomings of DDS and PLL.The scheme of the LFM signal source in X-band(10～11 GHz) is designed,and the frequency locked time and phase noise of signal source are simulated.Based on DDS chip AD9852,the source-driven PLL is further designed.
