Abstract
Radio communication apparatus comprising an antenna, a transmitting circuit of outputting a transmitting signal in a first frequency band. A duplexer connected to the antenna and having a single-phase input terminal and a balanced output terminal, conveying the transmitting signal inputted to the single-phase input terminal to the antenna. The duplexer outputs a receiving signal in a second frequency band different from the first frequency band received from the antenna substantially as a differential signal from the balanced output terminal. A receiving circuit connected to the balanced output terminal and having a circuit in which a gain of a signal of a differential component is higher than that of a signal of an in-phase component, or a loss of the signal of the differential component is lower than that of the signal of the in-phase component.
