Yet, above-mentioned coaxial cable multimedia connection (MoCA) though network technology can reach phone, network, cable TV (CATV), satellite is shared the expection effect that antenna system (Satellite Master AntennaTelevision System SMATV) and WLAN (WLAN) are incorporated into coaxial cable, but use discovery its whole execution, various signal by the coaxial cable transmission, after input multimedia wideband Wireless Router, it carries out the filtering action except need utilize the filter of different filter effects respectively in the use, to obtain outside the required frequency range, still need and intercept the frequency range of 975MHz～1525MHz, to meet the working frequency range of multimedia over Coax Alliance (MoCA), make when this multimedia wideband Wireless Router desires to be connected to TV or various different digital multimedia equipment, the different filter of all need arranging in pairs or groups, go up inconvenience greatly thereby cause to use, cause it still to have great room for improvement in integral body.

The utility model content

The utility model provides a kind of multi-media network filter, is studied improvement at existing structure and disappearance, to reach the purpose of better practical value.

The utility model provides a kind of multi-media network filter, low-pass filter circuit and bandwidth-limited circuit or low-pass filter circuit and high-pass filtering circuit are modularization to be arranged on the circuit board, and corresponding low-pass filter circuit is provided with first pin on circuit board, and corresponding bandwidth-limited circuit or high-pass filtering circuit are provided with second pin and the 3rd pin simultaneously.

By this, filter housing after this modularization can be arranged in the multimedia wideband Wireless Router, make multimedia wideband Wireless Router must not change different filters in response to different occasion demands, can connect TV or various different digital multimedia equipment, reaching the purpose that significantly reduces manufacturing cost and assembling man-hour, and its whole implement to use more increase practical value.
