It is possible to facilitate design and reduce a size and power dissipation of a radio frequency integrated circuit RFIC for full duplex system, by forming a duplexer for passing only a desired band, a low noise amplifier circuit LNA for amplifying an output signal of the duplexer, and a BPF for passing only a desired band in an output signal of the LNA in the same module and preventing a leak level of a transmission signal to a receiver side from affecting the design of the RFIC.
