摘要
频率源是所有通信系统的核心部件,频率源的信号质量直接决定着通信系统的好坏。文中选用高鉴相频率的HMC440芯片作为基本鉴相器,并通过分频器的巧妙设计实现了一种低相噪的跳频频率源。
Frequency synthesizer is the most important parts of all communication systems, because the quality of the frequency synthesizer affect whether all communication systems right or wrong.The paper introduces a design of hopping frequency systhesizer based on HMC440,which achieve the excellent low phase performance through a frequency dividers by five.
