The present invention comprises in a high frequency tuning method of the high-frequency plug connector, a printed circuit board having both RF connection contacts (21-28) and the insulation displacement connection contacts (31-38) (3). Each high-frequency connection for contact (21-28) is connected to each of the insulation displacement connection contacts (31-38). Electrostatic coupling that causes the near-end crosstalk is generated between the high-frequency contact. At least one first conductor path is connected only to the electrical connection contacts (26) one surface (46) is arranged on a printed circuit board (3), arranged on the printed circuit board and / or in the interior at least one second conductor path with (44) to form a capacitor _{(C 46)} was. Determined at least one frequency-dependent parameter of the device, the frequency-dependent parameter is compared to the set parameters, these according to the difference between the two is connected conductor on one surface (46) partially removed or to completely separate.
