Patent ID: 7257281

Claim:
A method for fabricating high frequency, low loss structures, the method comprising steps of: fabricating circuit layers on a first side of a first ceramic substrate to obtain a first circuit subassembly; fabricating other circuit layers on a first side of a second ceramic substrate to obtain a second circuit subassembly; printing a first metal layer on selected portions of a second side of the first ceramic substrate; drying the first metal layer; printing a second metal layer on selected portions of a second side of the second ceramic substrate; drying the second metal layer; printing a third metal layer on the second metal layer; aligning the first metal layer with the third metal layer; placing the first circuit subassembly on the second circuit subassembly to form a resultant assembly based on the aligning; drying the third metal layer; and, firing the resultant assembly, wherein the resultant assembly is a fiber optic transmitter.
