A portable computer can be \u201chot\u201d docked to one or more expansion devices, such as a drive wedge and a port replicator. In one example, the press fit passive component has a cylindrically shaped body with solderable terminals at either end of the body, and a dielectric collar disposed at least partially about the cylindrically shaped body. A carriage is mounted on the support by second track assemblies so that the carriage may travel in a second direction relative to the body. The output of the function or services is then recombined with the wideband signal.
