Abstract
An apparatus for terminating a transmission line includes a terminating circuit coupled to a first connector portion. A second connector portion mates with the first connector portion. The second connector portion is coupled in electrical contact with the transmission line and includes one or more components, such as pins, that can radiate unwanted electromagnetic interference (EMI) when the transmission line is not terminated. The terminating circuit includes components, such as one or more resistors, that substantially match the impedance of the transmission line. The terminating circuit can also be configured to terminate other conductive lines that can pick up signal noise in a system. The terminating apparatus can be utilized on operational boards that plug into devices such as backplanes or mid-planes. Alternatively, the terminating circuit can be included on a null device or built into the first connector portion.
