Abstract
A tunable inductor is provided, including an elongate mandrel having a central axis, and having a helical groove of predetermined pitch formed on an outer surface thereof. A flange having at least one guide member is also included proximate a first end of the mandrel and positioned substantially perpendicular the central axis thereof. A wire is also included, positioned within the helical groove and wound about the central axis of the mandrel, as well as a turn member positioned a distance from the flange in the axial direction and protruding from the outer surface of the mandrel. The turn member is radially offset from one guide member by an amount substantially equal to a diameter of the wire, and redirects the wire in a direction substantially parallel to the central axis of the mandrel from the helical groove back toward the first end of the mandrel.
