摘要：A network cable jack includes a printed circuit board (PCB) for balancing bothinductive and capacitive coupling. Using a PCB allows compact trace paths to be formedwithout significantly increasing manufacturing costs. By including on each trace path two
distinct inductance zones separated by a neutral zone, significant gains in degrees offreedom are achieved for designing PCB trace patterns in which a pair of inductivecoupling zones jointly offset the inductive coupling caused by a specification plug and thejack contacts, both in magnitude and phase angle. Further, using distinct inductance zonesoffers more freedom regarding the placement of capacitive plates for use in capacitancebalancing as well as the placement of terminals and insulation displacement contacts.Although the magnitude of a capacitive coupling is determined by the length of thecapacitor plates parallel to current carrying traces, the approach allows capacitive andinductive coupling to be balanced independently.
