Abstract
A system that incorporates teachings of the present disclosure may include, for example, determining an operational criteria associated with a modulation type of a signal modulation. A single write command is generated for applying a group of tuning steps to a matching network of a mobile communication device. The group of tuning steps are determined according to the operational criteria associated with the modulation type of the signal modulation. The single write command is transmitted to a switch controller coupled to the matching network for adjusting settings of the group of switches according to the group of tuning steps to generate a desired tuning value without multiple write commands. Additional embodiments are disclosed.
