A radio station providing a digital predistortion to be imposed on a payload signal is disclosed. The digital predistortion is usable as a digital predistortion for one or more of the transmit paths of the radio station. The radio station provides coupled transmit signals to be switched as a selected one of the coupled transmit signals along a common feedback path. A digital predistortion update unit is adapted to update the digital predistortions in order to linearise a transfer characteristics of the transmit paths according to a hierarchy of the transmit paths. A method of digitally predistorting a payload signal in order to linearise a transmit characteristics of the transmit paths is disclosed.
