Summary:A combined package shielding box for microwave filter comprises a box cover with gild layer and a box base, which is characterized in that a filter assembly welding board and a filter working patch are arranged inside the box base. The filter working patch with gild layer is first welded on the welding plane with gild layer on the welding concave plane of the filter assembly welding board in accordance with the welding layer, and the filter assembly welding board is fixed inside a cavity of the filter base. The utility model has the advantages that the proposal adopts the combined structure to improve assembling efficiency, the separate assembly of components reduces injury to the filter working patch in assembly process, the proposal solves problems of fixing shielding of the super-conduct filter, connection of external circuit, grounding, welding and assembly of the micro wire type filter and the welding concave plane of the filter assembly welding board in the filter package shielding box can guarantee the sufficient grounding and precise positioning of the filter working patch.
