Abstract
A system that incorporates teachings of the present disclosure may include, for example, determining, by a controller of a mobile communication device, a phase shift criteria and an amplitude shift criteria associated with a modulation being implemented by the mobile communication device. The controller can determine a group of tuning steps that satisfies the phase and amplitude shift criteria and that provides a desired tuning step for a matching network of the mobile communication device. Additional embodiments are disclosed.
