A system and method for digitally providing impedance mismatch compensation for a communications medium in a communications device. A method comprises producing a power amplifier (PA) output signal, providing the PA output signal to a digitally-controlled transmission line (DCTL), transforming a first load impedance to a second load impedance producing a DCTL output, and coupling the DCTL output to an antenna. The PA having the first load impedance and the transforming is controlled by a digital control word provided to the DCTL.
