More Information
Summary:The invention discloses a dielectric filter, a method for preparing the dielectric filter and communication equipment. According to the embodiment of the invention, the dielectric filter comprises: atleast two dielectric block combinations which are arranged side by side at intervals and respectively comprise at least two dielectric blocks which are arranged in a coplanar manner at intervals; a first dielectric coupling piece which is arranged between the at least two dielectric block combinations; and a second dielectric coupling piece which is arranged between at least two dielectric blockswhich are combined by the same dielectric block and are arranged adjacently in space so as to form a cross coupling path, wherein the at least two dielectric block combinations, the first dielectriccoupling piece and the second dielectric coupling piece are integrally sintered and formed, and materials of the dielectric filter at least comprise calcium carbonate, samarium trioxide, aluminum oxide and titanium dioxide.
