Abstract: A filtering apparatus includes a passband of a first-level unit which is formed by at least three coaxial filters covers a passband of a second-level unit which is formed by at least three dielectric filters, and a bandwidth of the first-level unit is twice the bandwidth of the second-level unit, so that when the coaxial filters are coupled to the dielectric filters, insertion loss of the coaxial filters is reduced, thereby reducing overall insertion loss of the filtering apparatus. By making a transmission zero of the first-level unit be located at a second harmonic frequency point of the second-level unit, the filtering apparatus can have high suppression on a second harmonic, thereby obtaining relatively desirable far-end suppression performance.
