Flexible printed circuit with radio frequency choke

An electronic device, comprising:

• at least one processor;
• a main circuit board on which the at least one processor is mounted;
• a flexible printed circuit comprising conductors disposed on a flexible substrate and including at least one planar portion;
• an image sensor coupled to the flexible printed circuit and configured to generate a differential signal that is transmitted over a pair of conductors in the flexible printed circuit;
• a connector configured to electrically interconnect the flexible printed circuit with the main circuit board so that the image sensor is operatively coupled to the at least one processor;
• a first radio frequency common-mode choke connected in series with the differential pair of clock signal conductors;
• and
• a second radio frequency common-mode choke connected in series with the differential pair of data signal conductors,
• wherein the first and second radio frequency common-mode chokes are mounted on the planar portion of the flexible printed circuit proximate to the connector.

An image sensor assembly, comprising:

• a flexible printed circuit including etched conductors disposed on one or more flexible substrate layers and including at least one planar portion;
• an image sensor mounted on the flexible printed circuit that is configured to generate differential clock and data signals that are transmitted on different respective pairs of conductors;
• a connector portion of the flexible printed circuit that is configured to enable the pairs of conductors to be connected to an external system;
• a first radio frequency common-mode choke connected in series with the differential pair of clock signal conductors;
• and
• a second radio frequency common-mode choke connected in series with the differential pair of data signal conductors,
• wherein the first and second radio frequency common-mode chokes are mounted on the planar portion of the flexible printed circuit proximate to the connector portion.
