Abstract: A multipole connector includes a housing having at least one conductive shell. Signal lines with pins extend through the housing, especially for carrying digitized signals. A base plate is disposed in the housing and is formed of aluminum-oxidic or ferromagnetic ceramic. A planar filter is mounted on the base plate in the housing. The planar filter has one capacitor for each of the pins of at least some of the signal lines. The capacitors are formed by a base electrode applied to the base plate, a dielectric layer applied onto the base electrode, and a counter electrode applied onto the dielectric layer. One of the electrodes is continuously constructed as a ground electrode and is conductively connected to the housing. The other of the electrodes is subdivided into individual signal electrodes and is conductively connected to the signal lines. The base plate, the dielectric layer and at least one of the electrodes have recesses formed therein forming ducts for the signal lines.
