A package for surface acoustical wave (SAW) device includes an electrically insulative substrate having a first surface with an electrically conductive layer formed thereon. A first surface of the SAW device is attached to the electrically conductive layer. An electrically conductive adhesive bead overlies the substrate first surface and surrounds the SAW device. An electrically conductive lid defines a free space over a second surface of the SAW device, the lid being electrically connected to the electrically conductive layer by the adhesive bead and one or more tabs extending from the lid through the adhesive bead to the electrically conductive layer. The electrically conductive adhesive bead, electrically conductive layer and electrically conductive lid enclose and shield the SAW device.
