摘　　要：针对抗干扰通信需求,提出了一种宽带高速跳频频率合成器的设计方案。在采用直接数字频率合成技术(Direct Digital Synthesis,DDS)实现了窄带高速跳频的基础上,通过与乒乓式切换的双频锁相环(Phase-Locked Loop,PLL)频率合成器混频的方式,提高了高速跳频频率合成器的输出频率,给出了宽带高速跳频频率合成器的详细设计思路与实现方案以及可靠性设计的相关内容。经过实际测试,测试结果达到了预期的指标要求。A novel wideband high-speed frequency-hopping frequency synthesizer is presented for anti-jamming communication. On the basis of using DDS to realize narrowband high-speed frequency hopping,the output frequency of frequency-hopping frequency synthesizer can be improved by the ping-pong type switching double PLL Frequency Synthesizer frequency mixing. The design scheme and implementation method of frequency-hopping frequency synthesizer are introduced in detail. The relevant content of reliability design is also presented. The test results show that the design can meet the expected requirements of specifications.
