甚高频信号源的设计

Design of UHF Carrier

为了给小型信标模拟器提供甚高频载波,利用锁相环(phase loop lock,PLL)频率合成原理,使用集成锁相频率合成器ADF4360-8设计甚高频(ultra high frequency,UHF)信号源,详述了电路的硬件设计,简要介绍了软件设计。实验结果表明,频率误差小于±0.002%,达到了预期的技术指标。

In order to provide UHF carrier for small navigation simulator, an integrated phase -locked frequency synthesizer ADF4360 - 8 was used to design UHF carrier signal source based on the theory of PLL. The hardware circuit was designed and the software was introduced. The experiment results show that the frequency error of margin is less than 0.002% ,which indicates that the design meets the technical specifications.
