摘　　要：AD9959是一款四通道的直接数字频率合成器,可以产生精确度很高的同频同相的信号,而且各通道之间有着良好的隔离性.根据这个特性可以设计一款具有超高的频率转换速度、精确的频率控制、极低的系统和相位噪声的高稳定度的频率综合器.既可以作为跳频雷达或者跳频电台的信号源,也可以作为一般的高精度信号源使用.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.
