利用DDS/PLL实现微波频率合成器

Using DDS/PLL for Designing A Microwave Frequency Synthesizer

阐述了新一代频率合成技术 直接数字频率合成技术（ＤＤＳ） 的原理， 并讨论了其与锁相环混合构成频率合成器的两种方案，

The principle of the new type of frequency synthesis (Direct Digital Synthesis, DDS)is introduced. Two methods of realizing frequency synthesizer with DDS and (PLL) Phase Locked Loop are discussed, and a microwave frequency synthesizer is designed.
