摘要
在无人机着陆系统中需要一种高频稳度的频率合成器,本文基于集成锁相环PE3240芯片设计了一种具有高频低相位噪声性能的频率合成器,并对影响相位噪声的因素进行了分析,电路测试结果表明设计达到了预期要求。
A high stability frequency synthesizer will apply to Unmanned Aerial Vehicle （UAV） landing system; a frequency synthesizer which based on the integrate phase locked loop PE3240 and had the performance of high frequency and low phase noise was designed in this paper, and the factors that affect the phase noise were analyzed; this design had reach the expected demand showed in the circuit debugging results.
