A method, wireless communication device, and a base station calibrate relative phase of a plurality of output signals from respectively combined plurality of transmitters (302, 204) in the wireless device (102, 108). An output of a combiner (346) is disconnected (504) from an antenna port (306) of a wireless device (102, 108). A phase position of an output signal from one of the at least two transmitters is set to an initial phase position value (506). The phase position of the output signal is incremented by a given phase increment value until a final phase position value is reached (510). Occurrences of reverse power alarm events are monitored at the initial phase position value, at each incremental phase position value, and at the final phase position value (512). A phase position value for the output signal is selected (516).
