Research on S-Band DDS-Driven PLL Low Spurious Frequence Synthesizer
View through CrossRef
In the development process of modern radio communication device, it is important of merits that the frequency of the generator performance, which can directly affect the performance of the communication device. In usual, often used to motivate phase-locked loop (PLL) to realize the broadband frequency synthesizer of low noise and direct digital synthesizer (DDS) of small step. This paper expounded a kind of technology that realized S-band DDS-driven PLL low spurious frequence synthesizer.Designed to get which the bandwidth of 250MHz and spurious suppression indicators meet the whole band is better than -65dBc.
