US Patent:

20040251230, Dec 16, 2004
Filed:

Jun 16, 2003
Appl. No.:

10/462447
Inventors:

Leonard Wardzala - Burlington WI, US
Gregory Ballard - Belvidere IL, US
Kurt Friel - Sycamore IL, US
International Classification:

H01B013/00
US Classification:

216/013000
Abstract:

A method for fabricating thick film alumina structures used in high frequency, low loss applications is provided. More particularly, the invention is directed to a co-fire process for fabricating, or laminating, thick film structures to one another by printing a conductor layer between two thick film circuits, drying the layer, and co-firing the combined structure. This process is particularly useful in fabricating high frequency (e.g. 10 gigabit) fiber optic transmitters.
