Abstract

See full text

An upper frequency-range circuit (160) includes a load element (168) exhibiting a capacitive load impedance. A first matching network (166) includes at least one nano-scale Litz wire (100) inductor. The first matching network (166) exhibits an inductive impedance that nominally matches the capacitive load impedance. An electrical conductor for providing connections for radio-frequency signals includes a plurality of nano-scale conductors (120) that are arranged in the form of a Litz wire (100). In one method of making a Litz wire (142), a plurality of carbon nanotubes (144) is placed on a substrate (146). The carbon nanotubes (144) are woven according to a predefined scheme so as to form a Litz wire (142). An inductor may be formed by manipulating the Litz wire (100) to form a coil (150).
