国创详解高通滤波器接线安装步骤-凯发k8手机网页

  高通滤波器是一种选频装置,可以使信号中特定的频率成分通过,而极大地衰减其他频率成分。那么在使用的过程中如何安装呢?看国创详解高通滤波器接线安装步骤!

  高通滤波器接线安装步骤:

  1.为了滤波器的安全可靠工作(散热和滤波效果),除滤波器一定要安装在设备的机架或机壳上外,滤波器的接地点应和设备机壳的接地点取得一致,并尽量缩短滤波器的接地线。

  若接地点不在一处,那么滤波器的泄漏电流和噪声电流在流经两接地点的途径时,会将噪声引入设备内的其他部分。其次,滤波器的接地线会引入感抗,它能导致滤波器高频衰减特性的变坏。所以,金属外壳的滤波器要直接和设备机壳连接。如外壳喷过漆,则必须刮去漆皮;若金属外壳的滤波器不能直接接地或使用塑封外壳滤波器时,它与设备机壳的接地线应可能的短。

  2.滤波器要安装在设备电源线输入端,连线要尽量短;设备内部电源要安装在滤波器的输出端。若滤波器在设备内的输入线长了,在高频端输入线就会将引入的传导干扰耦合给其他部分。若设备内部电源安装在滤波器的输入端,由于连线过长,也会导致同样的结果。

  3.确保滤波器输入线和输出线分离

  若滤波器输入、输入线捆扎在一起或相互安装过近,那么由于它们之间的耦合,可能使滤波器的高频衰减降低。若输入、输出线必须接近,那么都必须采用双绞线或屏蔽线。

  4.要将噪声滤波器正确地连接到设备内部的每一单元。

  若带有单独电源的若干单元安装在一个机壳内,那么必须把每一个单元视为设备的独立部分。每一单元必须连接各自的噪声滤波器,否则在机壳内,这些单元中的每一单元的噪声都会传导给其他单元。
