Abstract
Inductor topologies for filters used in broadband applications are described. In one implementation, an apparatus, such as an interface module includes a printed circuit board and a filter. The filter includes a generally circular high Quality factor (Q) value spiral planar inductor etched directly into the printed circuit board. The generally circular high Q value spiral planar inductor is configured to operate in a broadband application. Other implementations involve the use of decoupling structures with respect to the planar inductors as well as a design methodology for the filters.
