摘要
针对现代电子系统中的频率自动控制需求,文中基于锁相环实现了900~2100 MHz的频率合成技术,系统采用MSP430作为控制核心,通过硬件互联,串口通信实现了对ADF4113芯片的精确控制。本系统经实际测试,在工作频段内信号质量良好,满足设计指标要求。
With the development of modem electric systems, in order to satisfy the requirement of automatic frequency control, a frequency synthesis technology of 900-2100MHz based on PLL is realized in this paper. The system uses MSP430 as the control core, achieving the precise control of the ADF4113 chip. After the test of the system,we can make sure that our system can meet the design needs.
