超低相位噪声精密超临界切割的微型14x21x7.5毫米贴片封装的OCXO
其实如今随着电子产品性能的提升以及体积小型化等优化动作,现在的电子产品对石英晶振等频率控制元件的性能需求也越来越高;不知诸位有没有发现,近两年各大晶振厂家正在疯狂的研发晶振生产技术,纷纷推出一系列高性能的晶振产品,比如去年KDS晶振就推出了一款号称是业内最小的1008差分晶振;今年年初,NDK晶振也出产了带有低相噪性能的温补晶振等等,这样的事情在晶振行业中每天都在发生着,这就是当今晶振行业的一个详情.并且上个月NEL晶振又出产了一款超低相位噪声精密超临界切割的微型14x21x7.5毫米贴片封装的OCXO(恒温晶振).
该有源晶振的特征如下:
① 切割水晶
② 超低相位噪声
③ 正弦波+15 dBm输出
④ 极小的超薄包装
该石英晶体振荡器的应用范围如下:
① 使用仪器
② 雷达
③ 高端合成器
④ 电信系统
⑤ 数据通信
该SMD晶振的部分参数规格如下:
