ABSTRACT:
A grounding member for installation between a surface acoustic wave filter package and a circuit board to which the filter package is mounted. The grounding member is formed from electrically conductive sheet stock material as a leaf spring which is deformed to maintain effective contact between the outer case of the filter package and a ground plane on the circuit board. In addition to providing an effective ground connection between the filter package and the ground plane, the grounding member also functions as an electromagnetic shield for radiating signals between the input signal post and the output signal post of the filter package.
