1. A mobile communication device, comprising:

  • an antenna;

    a transceiver coupled with the antenna;

    a matching network coupled with the transceiver and the antenna, wherein the matching network includes a variable reactance element; and

    a controller coupled with the matching network, wherein the controller determines a desired tuning step to be applied to the matching network to adjust a variable reactance of the variable reactance element, wherein the controller determines a phase shift criteria associated with a modulation being implemented by the mobile communication device, and wherein the controller selects a group of tuning steps that satisfies the phase shift criteria and that provides the desired tuning step.
