Abstract
Disclosed is a structured hybrid different-wavelength resonant ceramic filter, comprising a ceramic substrate and an input/output electrode, wherein the ceramic substrate comprises a first surface and a second surface opposite to the first surface, five first resonant cavities, two second resonant cavities and two third resonant cavities are formed between the first surface and the second surface in a horizontal direction; the five first resonant cavities are located in the middle of the first surface of the ceramic substrate, the two second resonant cavities are respectively located at both sides of the five first resonant cavities, and the two third resonant cavities are respectively located lateral relative to the two second resonant cavities. With the present disclosure, filters with various forms and functions are integrated into a multi-cavities filter, and it is simple in structure.
