1. A modulized wave filter, comprising:

  • a circuit board, the circuit board including a first low-pass wave-filtering circuit;

    the circuit board including a band-pass wave-filtering circuit consisting of both a high-pass wave-filtering circuit and a second low-pass wave-filtering circuit;

    the first low-pass wave-filtering circuit being connected to the high-pass wave-filtering circuit;

    the circuit board including an input terminal directly coupled to a first switching component;

    wherein the first switching component is movable to a selective position for electrically connecting the input terminal and a node between the first low-pass wave-filtering circuit and the high-pass wave-filtering circuit;

    the circuit board including two output terminals, which are connected to the first and the second low-pass wave-filtering circuits respectively;

    the circuit board including a second switching component movable to a selective position for electrically connecting the high-pass wave-filtering circuit and the second low-pass wave-filtering circuit.
