    • There is provided a radio frequency circuit device for multi-band and multi-mode which is low in a circuit loss, and a mobile communication terminal using the radio frequency circuit device. The radio frequency circuit device has a first path 110 that includes an amplifier 10a that amplifies signals of at least two modulation techniques in power, a matching network 20 that is connected to the amplifier and a duplexer 50 and allows the matching network to be coupled with an antenna, and a second path 111 that does not include the duplexer and allows the matching network to be coupled with the antenna. The first path is selected when the amplifier amplifies one of the signals of at least two modulation techniques, and the second path is selected when the amplifier amplifies another signal. An output impedance of the amplifier is matched with an impedance when viewing the antenna side from the amplifier in the first path and the second path.
