Abstract: A duplexer of the present invention includes a reception filter (3) for passing signals in a predetermined frequency band and attenuates signals in the other frequency bands among reception signals input to an antenna port, and a transmission filter (4) for passing signals in a predetermined frequency band and attenuates signals in the other frequency bands among transmission signals input from the outside and outputting them to the antenna port. The duplexer further includes a conversion circuit (22) provided with a single-ended input terminal connected to the antenna port and balanced output terminals. The reception filter (3) is provided with a balanced input terminal connected to the output terminal of the conversion circuit (22) and a balanced output terminal for outputting the filtered reception signal. Thus, a balance-output-type duplexer that is connectable to a balance-input-type LNA and is free from loss and degradation in power-handling capability, a communication module and a communication device can be realized.
