PURPOSE: A transceiver is provided to transceives and receives a signal through optimized path. CONSTITUTION: A DCA(Digital Control Attenuator)(6) reduces an electricity of a filtered signal when the device is a transmission mode. A second amplifier amplifies a signal reduced the power when the device is a transmission mode. A second band pass filter(8) filters a signal amplified by a second amplifier when the device is the transmission mode. A power amplifier(10) amplifies power of a signal which is filtered by a second band pass filter when the device is transmission mode.
