Abstract: A front end module of a triple band terminal is provided to improve matching characteristics of an input impedance by providing an impedance matching inductor at input terminals of the second LPF(Low-Pass Filter) and an HPF(High-Pass Filter). The first LPF(410) extracts a signal of the first band from a signal received via a single antenna(400). A capacitor(C2) allows a signal of a high band frequency which has not been extracted by the first LPF(410) to pass therethrough. The second LPF(420) extracts a signal of the second band among signals which have passed through the capacitor(C2). An SAW(Surface Acoustic Wave) filter(440) extracts a signal of the second band from an output signal of the second LPF(420). An HPF(430) extracts a signal of the third band among signals which have passed through the capacitor(C2). An inductor(L3) for matching impedance is formed at a connection point to which the capacitor(C2), the second LPF(420) and the HPF(430) are connected.
