摘　　要：通过对频率合成方式进行分析,提出了一种新颖的L波段宽带频率捷变频率综合器设计方案。利用DDS电路产生的窄带频率捷变信号与数字锁相环电路产生的宽带跳频信号有机结合,并通过混频器及滤波器的合理设计,实现了宽带频率捷变。L波段宽带频率捷变频率综合器取得良好的实际工程应用效果,并对其它频率综合器的设计具有较高的参考借鉴价值。Based on the analysis of frequency synthesis approach, a novel L-band frequency agility Broadband frequency synthesizer is designed. Organic combination of DDS circuit generated by the signal narrow-band frequency agility and digital phase-locked loop circuit generated by broadband frequency hopping signals, and through the rational design of mixer and fil- ter, achieves broadband frequency agility, the L-band frequency agility broadband frequency synthesizer has achieved good results in practical engineering applications, and has a high reference value to other frequency synthesizer design.
