Patent ID: 6838956

Claim:
A filter assembly comprising: a ceramic substrate; a die including a film bulk acoustic resonator receive-band filter, positioned on the ceramic substrate, having an input and an output, and including a plurality of film bulk acoustic resonators; a first and a second loop of current, the first loop including a first wire bond connected to the input of the die, and a second wire bond connected to a first one of the plurality of film bulk acoustic resonators, the second loop including a third wire bond connected to the output of the die, and a fourth wire bond connected to a second one of the plurality of film bulk acoustic resonators, wherein the first loop induces parasitic current in the second loop; and wherein the first and the second wire bonds are positioned proximate to one another to minimize the area of the first loop, and the third and the fourth wire bonds are positioned proximate to one another to minimize the area of the second loop.
