Jan 31, 2011

Appl. No.:

13/018175

Inventors:

Stephen D. McNally - San Diego CA, US

Assignee:

DJM Electronics, Inc - San Diego CA

International Classification:

H05K 9/00

US Classification:

361818, 361816, 361789

Abstract:

Provided herein are methods, devices, and systems that relate to electromagnetic interference (EMI) filters that, in certain embodiments, comprise: (a) a housing comprising a substantially enclosed first compartment and a substantially enclosed second compartment; (b) a first circuit card located in the first compartment of the housing that converts a signal transmitted on a conductive based medium to a signal transmitted on a non-conductive based medium; (c) a second circuit card located in the second compartment of the housing that converts a signal transmitted on a non-conductive based medium to a signal transmitted on a conductive based medium; (d) at least one non-conductive based medium that transmits a signal from the first circuit card to the second circuit card; and (e) at least one waveguide through which the non-conductive based medium passes from the first compartment to the second compartment.
