3.3 滤波器的安装滤波器在实际应用环境中的工作性能完全取决于其安装的方式,尤其是射频参考地的阻抗和滤波器到射频地的搭接阻抗。这些阻抗必须远远低于滤波器内并联电容的阻抗,同时,滤波器内部与外部的共模表而电流也必须具有最佳的返同路径。3.3.1 输入与输出导线滤波器经过输入与输出两端导体之间的杂散射频 3.3 Filter Installation Filter performance in practical applications depends entirely on the way it is installed, especially RF reference ground impedance and filter to RF ground strap impedance. These impedances must be well below the impedances of the shunt capacitors in the filter. At the same time, the current inside and outside the common-mode filter must be returned to the same path. 3.3.1 Inputs and Outputs The line filter passes the spurious RF between the input and output conductors
