Abstract
In a circuit assembly of two connectors and a printed circuit board positioned between them, a parasitic reactive coupling is created by the connectors. In the circuitry of the circuit board a compensating reactive coupling is provided. This is at least partly formed by lengths of conductor path in the board, which lengths are spaced apart with a specific gap aver a certain distance along the lengths to give a desired inductive compensating coupling. If required, the compensating reactive coupling also includes capacitors provided by capacitor plates forming parts of different conductor paths on opposite sides of the board.
