Abstract
Abstract Apparatus and method for mechanically and electrically coupling an acoustical surface wave device to an electronic circuit. The apparatus includes a gasket and a housing. The gasket, comprised of a resilient material having conducting regions, provides electrical coupling between, while physically separating, the electronic circuit and the surface wave device. The housing locates the gasket relative to the surface wave device and to the electronic circuit so that preselected regions of conductivity of the assembly are adjacent. The housing further provides mechanical coupling of the surface wave device and the gasket to the electronic circuit and, by exerting sufficient force to compress the gasket, assures electrical coupling between the adjacent conducting regions. The gasket, disposed around the periphery of the surface wave device, damps acoustical surface waves reaching the periphery, thereby reducing edge-reflected acoustic surface waves, while not affecting the production and propagation of desired surface wave components. The gasket further acts as a seal, protecting the active portion of the surface wave device.
