Abstract
Transmission outputs of a plurality of transmission branches () are extracted by coupler sections (). Branch detectors () respectively detect the levels of the extracted signals of the respective transmission branches and a combination detector () detects an output obtained by combining two extracted outputs from the transmission branches by a signal combining section (). An amplitude error is detected and corrected by comparing output levels of the branch detectors (), and a phase error is detected and corrected by an output level of the combination detector ().
