数字频率合成技术在地球站中的应用

The Application of Digital PLL Frequency Synthesizer in Ground Station

数字分频式微波频率合成器,具有结构简单,造价低,良好的低相嗓特性等优点,因而被通信卫星地球站所广泛采用。论述了数字分频式频率合成技术在工星通信地球站中的应用,提出了采用高度集成锁相环器件:PE3336设计一种低相噪特性的微波数字频率源的工程实例,并将之用于某通信卫星转发器地球站设备中。

Digital PLL frequency synthesizer has the simple structure, low cost, and preferable phase noise characteristics, which make it being widely, used in communication satellite earth station systems. The application of digital PLL frequency synthesizer in communication satellite earth station was discussed. Furthermore this paper also gaves an engineering example using a high integration PLL: PE3336 to design a PLL frequency synthesizer with Ultra - low phase noise, and it had been used in a sort of communication satellite transponder earth station system.
