The present invention provides a radio system and a method for relaying radio signals, providing a power calibration of transmit radio signals. With the radio system and the method no dedicated calibration signal generator is required for providing the power calibration of the transmit radio signals. The radio system comprises at least one transmit path, a calibration unit at the least one link and a power sensor. A selected one of coupled transmit signals is forwarded to a power sensor for measuring a power level of a portion of the selected one of the coupled transmit signals, wherein the calibration unit is adapted to update a power rating of the at least one transmit path in response to the transmit power level of the selected one of the coupled transmit signals.
