Low-Loss Shielded Radio-Frequency Inductor
In one aspect, described is a magnetic-core inductor design approach that leverages NiZn ferrites with low loss at RF, distributed gaps and field balancing to achieve improved performance eat tens of MHz and at hundreds of watts and above. Also described is an inductor design which achieves “self-shielding” in which the magnetic field generated by the element is wholly contained within the physical volume of the structure rather than extending into space as a conventional air-core inductor would. This approach enables significant reductions of system enclosure volume and improvements in overall system efficiency.
