The invention provides a network port transformer adopting an electronic circuit structure to replace a magnetic core coil. The network port transformer comprises a coupling module, a filtering module and a protecting module; the coupling module is used for carrying out bidirectional coupling on high-speed network signals and isolating DC (Direct Current) signals; the coupling module adopts a capacitive coupling mode, the coupling module is provided with a plurality of groups of capacitive coupling units, and each capacitive coupling unit is respectively provided with a group of capacitance bodies; the filtering module is used for filtering high-frequency useless signals in the network signals; and the filtering module adopts a Bessel type stop band filter and/or a quasi Bessel type TRACE filtering structure. The network port transformer adopts the electronic circuit structure to achieve functions of coupling, filtration and protection of the transformer and completely replace a conventional magnetic core coil structure, and is a basic novel network port transformer which is suitable for automatic production and is low in labor cost, high in qualified rate of finished products and strong in competitiveness.
