Abstract

The present invention relates to a network signal coupling circuit, which is arranged on a circuit board and is a signal coupling circuit for coupling signals transmitted between a network connector and a network chip. The signal coupling circuit is provided with a plurality of channels respectively having two circuits , one or more channels are connected with a coupling module, and the coupling module is connected with a first capacitor in a circuit, or an equivalent resistance is connected in parallel at the two ends of the first capacitor, and then the other end of each equivalent resistance is electrically connected Connected to the signal equivalent ground terminal, the capacitive reactance will decrease with the higher the frequency, so that the attenuation of the signal will also become smaller, and the characteristics of the capacitive signal coupling will be better with the higher the frequency, so that the network The signal coupling circuit still has a good network signal coupling effect when used at a high network frequency, thereby achieving the purpose of improving signal coupling and transmission effects.
