Ceramic medium filter

The utility model discloses a ceramic medium filter, mainly used for a mobile communication receiving system. The ceramic medium filter is manufactured by employing the SIR technology and lamination and static pressure process and comprises the steps of tape casting diaphragm manufacturing, mechanical punching and diaphragm processing, i.e., a complex structure of a resonator in a filter is decomposed into a plurality of single layer structures; the single layer structures are then suppressed and moulded by the lamination and static pressure process, thereby overcoming shortcomings of a traditional preparation method and preparing a high end medium filter with a complex shape and high performance. The ceramic medium filter has reduced dimension and weight, raises out-of-band rejection, reduces filter cost and raises reliability.
