Abstract
Increasing performance of planar inductors used in broadband applications is described. In one implementation, an apparatus includes a high Quality factor (Q) value spiral planar inductor etched directly into a printed circuit board. A ferrite structure is attached to the printed circuit board and located in proximity to the high Q value spiral planar inductor. The ferrite structure increases the Q of spiral planar inductors, but without the inconvenience and expense of a wire wound terroidal inductors. Various shaped ferrite structures may be used in conjuction with the spiral planar inductors. Additionally, in certain implementations, the ferrite structures are configured to rotate about axis permitting the inductors to be tuned, even after components have been installed on a printed circuit board.
