Transmission line and filtering module thereof

摘要

A transmission line includes a signal terminal for inputting a first signal and a second signal, a first wire coupled to the signal terminal for transmitting the first signal, a second wire coupled to the signal terminal for transmitting the second signal, a filtering module coupled to the first and second wires for receiving the first and second signals to filter out noises of the first and second signal, a third wire coupled to the filtering module for transmitting the first signal, and a fourth wire coupled to the filtering module for transmitting the second signal.

1. A transmission line, comprising:
a signal terminal for inputting a first differential signal and a second differential signal; a first wire coupled to the signal terminal for transmitting the first differential signal; a second wire coupled to the signal terminal for transmitting the second differential signal; a filtering module coupled to the first and second wires for receiving the first and second signals to filter out noises of the first and second differential signals; a third wire coupled to the filtering module for transmitting the first differential signal; and a fourth wire coupled to the filtering module for transmitting the second differential signal; wherein the filtering module comprises:
a first differential choke coupled between the first and third wires for filtering out a differential mode noise of the first differential signal; anda second differential choke coupled between the second and fourth wires for filtering out a differential mode noise of the second differential signal;wherein, the first and second differential chokes are dual in-line package (DIP) differential chokes.
