Abstract
A reflected signal detector () detects the amplitude and the phase of a reflected signal and outputs detection signals. A control circuit () adjusts first control signals and second control signals on the basis of the detection signals. A first cancel signal output portion () adjusts a first cancel signal so that the first cancel signal has a phase opposite to that of the reflected signal and has the same amplitude as that of the reflected signal using the first control signals. A second cancel signal output portion () adjusts a second cancel signal so that the second cancel signal has a phase opposite to that of a leakage signal and has the same amplitude as that of the leakage signal using the second control signals. A combining portion () combines a reception signal including noise signals with the first and second cancel signals.
