Increasing performance of planar inductors used in broadband applications

An apparatus, comprising:

• a filter configured to operate in a broadband application, comprising:
• a generally circular high Quality factor (Q) value spiral planar inductor etched directly into a printed circuit board;
• a hole positioned within one or more layers of the printed circuit board;
• and
• a ferrite structure positioned within at least a portion of the hole;
• wherein the ferrite structure includes a post connected to a pedestal structure, wherein the post is configured to fit inside the hole and the pedestal structure is configured to reside outside the hole.

An apparatus, comprising:

• a printed circuit board;
• a filter, operable in a broadband communication interface application;
• the filter comprising a high Quality factor (Q) value spiral planar inductor having generally circular conductive traces etched directly into the printed circuit board, wherein an outer most conductive trace wraps around inner conductive traces that form a spiral leading to an inner most conductive trace, wherein the inner most conductive trace wraps around a center portion of the inductor, the center portion having no conductive traces;
• and
• a ferrite structure fastened to the printed circuit board and covering at least a portion the high Q value spiral inductor;
• wherein the printed circuit board includes a hole passing through one or more layers of the printed circuit board, the hole positioned within the center portion of the high Q value spiral inductor, and the ferrite structure is fastened to the printed circuit board via the hole.
