PROBLEM TO BE SOLVED: To provide a radio communication device capable of appropriately calculating the calibration coefficient of each transmission/reception branch by suppressing the difference in the acquisition timing of a loopback transfer function in transmission/reception directions. SOLUTION: The radio communication device includes: a loopback transfer function acquisition section 163 for acquiring a loopback transfer function for each route included in a first route, based on the reception situation of a reference signal transmitted from each branch of a first group and received by each branch of a second group while the first route including all routes reaching each branch of the second group has been formed from each branch of the first group via an antenna, and acquiring a loopback transfer function for each route included in a second route, based on the reception situation of a reference signal transmitted from each branch of the second group and received by each branch of the first group while the second route opposite to the first route has been formed; and a calibration coefficient acquisition section 164 for calculating a calibration coefficient for each transmission/reception branch, based on the acquired loopback transfer function.
