A quintplexer is provided to separate and maintain each frequency band signal stably without interference by suppressing a leakage current among adjacent circuits at maximum by adopting an LC tank and a phase shifter. A first choke circuit(110) blocks a first signal and passes a second signal and a third signal by being connected to an antenna(200). A first signal separation part(120) is connected to the antenna, and includes a second chock circuit(122) blocking the second signal, a third chock circuit(124) blocking the third signal and a separator(126) separating transmission and receiving bands of the first signal. A second signal separation part(130) blocks the third signal and separates transmission and receiving bands of the second signal among signals transferred from the first choke circuit. A third signal separation part(140) includes a fourth choke circuit(142) blocking the second signal among signals transferred from the first choke circuit, and a filter(144) filtering the third signal. |
