A quintplexer is provided to minimize an insertion loss of each frequency band, and stably perform transmission/reception function by reducing the overall path loss. The first phase shifter(110) adjusts impedance of the third signal band received from an antenna. The second phase shifter(120) is connected with the first phase shifter and adjusts impedance of the second signal band. The third phase shifter(140) is connected with the first phase shifter(110) and adjusts impedance of the first signal band. The fourth phase shifter(160) is connected with the antenna and adjusts impedance of the first and second signals bands. The first duplexer(130) is connected with the second phase shifter(120) and separates transmission/reception signals of the first signal. The second duplexer(150) is connected with the third phase shifter(140) and separates transmission/reception signals of the second signal.
