Abstract

A matching network of a communication device that incorporates teachings of the present disclosure may include, for example, a controller that executes instructions facilitating an identifying a subset of usage scenarios based on a usage condition of the communication device and adjusting the matching network device based on a subset of different tuning scenarios corresponding to the subset of usage scenarios. A group of operational parameters is obtained via parametric measurements for each tuning scenario change between the tuning scenarios corresponding to each of the subset of usage scenarios. Multiple operational parameters are averaged corresponding to each of the tuning scenarios to identify an average operational parameter for each tuning scenario, and a tuning scenario is selected from among the subset of different tuning scenarios based on a determination as to which of the average operational parameters correlates with a desired performance goal. Additional embodiments are disclosed.
