Patent ID: 7466210

Claim:
A surface acoustic wave oscillator module, comprising: a single substrate having a top surface, a bottom surface and an outer peripheral edge; a plurality of castellations located about the outer peripheral edge, the castellations forming an electrical connection between the top surface and the bottom surface; at least one metallized slot located about the outer peripheral edge; at least one connection pad mounted on the top surface of said single substrate and connected to at least one of the castellations; an oscillator circuit mounted on the top surface of said single substrate and connected to at least one of the connection pads; a surface acoustic wave device hermetically sealed in a package, the package being mounted to the top surface of said single substrate and connected to at least one of the connection pads and coupled to the oscillator circuit; and a cover having at least one tab, the cover mounted to the top surface of the substrate, the tab being adapted to be fitted within the metallized slot, the tab and the metallized slot forming an electrical connection between the cover and the metallized slot.
