A system that incorporates teachings of the present disclosure may include, for example, a matching network having one or more controllable variable reactive elements coupled to at least one input port and at least one output port. The one or more controllable variable reactive elements can be adapted to increase power transferred from the at least one input port to the at least one output port responsive to signals generated by a controller adapted to adjust one or more reactances within the matching network according to a mode of operation of a device detected by the controller. Additional embodiments are disclosed.
