摘要
X波段线性调频信号源已在多个领域得到广泛应用。采用直接数字频率合成(DDS)激励锁相频率合成(PLL)的技术,可以弥补各自的缺点,设计了X波段(10GHz～10.5GHz)线性调频信号源的实现方案,并对信号源的频率建立时间和相位噪声进行了仿真,重点研究了基于AD9854的锁相环激励信号源的设计。
X-band LFM signal source is widely applied in many areas.On the basis of DDS-driven PLL,this paper makes up for their short comings,the scheme of the LFM signal source in X-band（10GHz～10.5GHz） was designed.The frequency locked time and phase noise of signal source were simulated.Based on AD9854,the source-driven PLL was further designed.
