Patent ID: 7414496

Claim:
A filter structure comprising: a filter including a bulk acoustic wave filter or a thin film resonator filter comprising an input port and an output port, wherein the input port includes a first pad for receiving an input signal of the bulk acoustic wave filter or thin film resonator filter and a second pad for a first reference potential to which the input signal is related, and wherein the output port comprises a third pad for outputting an output signal of the bulk acoustic wave filter or thin film resonator filter and a fourth pad for a second reference potential to which the output signal is related, and wherein the second pad and the fourth pad on the filter are isolated from each other; a carrier comprising a reference potential area; a first connecting wire contacting the second pad at a first connection point and contacting the reference potential area at a second connection point; and a second connecting wire contacting the fourth pad at a third connection point and contacting the reference potential area at a fourth connection point, wherein a first distance between the second connection point and the fourth connection point is smaller than a second distance between the first connection point and the third connection point.
