频率源

概述
    频率合成源是微波系统的重要功能单元,在收发信机、雷达探测、通信、检测仪器等电子设备中被广泛使用。
    从普通VCO、介质振荡器(DRO)、同轴振荡器(CRO)、钇铁石榴石振荡器(YIG)中选择合适的振荡器配以各种合成技术,从而为您提供性价比最高的频率合成源。配以大洋微波开发的先进的开环预置、闭环实时修正等辅助捕获技术,可为您提供极短的频率转换时间。

 

 产品分类:
连续扫频源--采用开环校正技术,闭环校正技术可使扫频线性度小于0.1%。
直接式模拟倍频源--优良的相位噪声性能,混频后附加相位噪声小于5dB。
DDS数字频率合成源--变频时间短、Hz级频率步进、优良的相位噪声。

单环锁相源--单环锁相可采用整数分频或者小数分频。此种频率源结构简单,体积小,功耗低。

混合锁相--采用多环锁相技术,结合DDS并配以闭环实时修正辅助捕获技术,可获得高性能的相位噪声以及快速跳频。
