Patent ID: 8476755

Claim:
A high frequency ceramic package comprising: a conductive base plate; a ceramic RF substrate placed on the conductive base plate; a first conductive pattern placed on the top surface of the ceramic RF substrate; a plurality of second conductive patterns placed on the bottom surface of the ceramic RF substrate; a plurality of through holes for passing through the top surface and bottom surface of the ceramic RF substrate; a plurality of through hole metal layers filled in the plurality of through holes and which connect the first conductive pattern and the plurality of second conductive patterns; a ceramic seal ring placed on the ceramic RF substrate; an insulating adhesive bond placed on the ceramic seal ring; a ceramic cap placed on the insulating adhesive bond; and a plurality of conductive leads connected with the plurality of second conductive patterns, the plurality of conductive leads and the conductive base plate being placed in the same plane and separated from each other, wherein the plurality of second conductive patterns is used as external terminals, and between the ceramic cap and the top surfaces of the ceramic seal ring is sealed with the insulating adhesive bond.
