METHOD FOR HIGH FREQUENCY SYNCHRONIZATION OF AN ELECTRIC SYSTEM AND AN ELECTRONIC BOARD USED FOR THAT PURPOSE Russian patent published in 2007 - IPC H04B15/02 H05K1/16 H05K1/18 

FIELD: technology for high frequency synchronization of an electric system and an electronic board used for that purpose.

SUBSTANCE: during realization of high frequency adjustment method, high frequency plug socket (1) is used, comprising electronic board (3), which has two types of contact points: points (21-28) for high frequency contacts and points (31-38) for contacts with isolation shift, each contact point (21-28) for high frequency contacts is connected to corresponding contact point (31-38) for isolation-shifting contacts, between high frequency contacts capacity connections appear, causing generation of cross inductions on near end of communication line. At least one first conductive track (46), connected on one side to contact point (26) of electric contact, is placed on electronic board (3) together with at least one second conductive track (44), positioned on electronic board (3) and/or inside it, forms capacitor (C₄₆). At least one frequency-dependent parameter of device is measured and compared to set parameter, and depending on the difference produced as a result of comparison, conductive track (46), contacting on one side, is removed partially or fully.

EFFECT: creation of method for synchronization of high frequency plug socket, in particular, RJ-45 socket, with at least one electronic board, and also creation of an electronic board, which allows adjustment of high frequency characteristics within a narrow tolerance range.
