Document Type and Number:
Japanese Patent JP5933471
Kind Code:
B2
Abstract:
Transmission output detectors 161, 162 extract transmission outputs of a plurality of transmission branches 101, 102, and an inter-branch error detector 110 detects a combined signal level of the transmission outputs of the transmission branches to obtain an error detection signal. A correction controller 130 calculates an amplitude error between the transmission branches based on an error detection signal which is obtained by turning ON/OFF output operations of the transmission branches 101, 102, and calculates a phase error between the transmission branches based on an error detection signal which is obtained by changing the phases of the transmission branches 101, 102. A phase controller 180 and an amplitude controller 190 correct the amplitude error and the phase error. The inter-branch error detector 110 can be configured by a simple circuit which is formed by a detector, and which can be mounted in a small size and low power.
