基于锁相环（PLL）L波段的频率合成技术

摘要

Frequency synthesizer is the core component of the electronic equipment,the performance of the performance of the overall performance of the electronic equipment.In this paper,a phase locked loop frequency technique based on phase locked loop (PLL) L band is studied.Its design scheme uses MC145152 to realize the phase locked loop,the external loop filter LPF and the voltage controlled oscillator VCO and other devices to achieve,with a strong research and design value.%频率合成器是电子设备的核心部件，其性能的优劣影响电子设备的整体性能。本文研究了一种基于锁相环（PLL）L波段的锁相频率技术。其设计方案使用MC145152来实现锁相环路，外加环路滤波器LPF和压控振荡器VCO等器件来实现，具有较强的研究设计价值。
