1. A low-pass filter comprising:

  • a first input/output port;

    a second input/output port;

    a first LC parallel resonator and a second LC parallel resonator connected in series and provided between the first input/output port and the second input/output port;

    a first path;

    a second path; and

    a third path, whereinthe first LC parallel resonator has a first end that is closest to the first input/output port in circuit configuration,the second LC parallel resonator has a second end that is closest to the second input/output port in circuit configuration,the first path includes a first LC series resonator and connects the first end to a ground,the second path includes a second LC series resonator and connects the second end to the ground,the third path includes a third-path capacitor and connects a connection point between the first and second LC parallel resonators to the ground, andthe third path has an inductance lower than an inductance of each of the first path and the second path.
