Design of fast frequency hopping synthesizer based on AD9959
SI Xi-cai · Applied science and technology · 2009
AD9959 is a direct digital frequency synthesizer with four channels.It can provide high-precision signal which has the same frequency and the same phase.Any one of the channels has low effect on others,so a very stable frequency synthesizer can be designed as having fast frequency hopping speed,exact frequency control,very low system and phase noise.It can not only be used as the signal source in frequency hopping radar or frequency hopping radio,but also as a high-precision signal source.
