Abstract:
1. A filter package comprising: a support structure; a filter device having plural terminals; impedance matching circuits formed on the support structure and electrically connected to at least some of the plural terminals of the filter device; at least one electrical ground structure electrically connected to the impedance matching circuits, wherein the at least one electrical ground structure is electrically connected to the impedance matching circuits using one or more of: (1) wire bonding the at least one electrical ground structure to the impedance matching circuits, and (2) electrically contacting the at least one electrical ground structure to the impedance matching circuits; and an outer housing containing the support structure, the filter device, the impedance matching circuits, and the at least one electrical ground structure, wherein the electrical ground structure includes a ground plane having openings, and wherein the impedance matching circuits include impedance matching lines provided in the corresponding openings of the ground plane so that the impedance matching lines are in a same plane as the ground plane.
