Abstract

A system that incorporates teachings of the present disclosure may include, for example, a matching network including a tunable reactance circuit configured to be coupled to at least one of a transmitter portion and a receiver portion of a communication device, where the tunable reactance circuit is adjustable to a plurality of tuning states, and where the determination of a tuning state is based on whether detected signal measurements are determined to be invalid and is based on information from at least one of an open-loop or closed-loop feedback configuration of the tunable reactance circuit. Additional embodiments are disclosed.
