Abstract
A system that incorporates teachings of the present disclosure can include, for example, determining at a port of a matching network reflection information from a signal sampled across at least one predetermined fixed-value reactance component, generating at least one control signal according to the reflection information, and tuning the matching network with the at least one control signal, where the matching network comprises one or more controllable variable reactive elements each with an independent control voltage. Additional embodiments are disclosed.
