Abstract:
An apparatus for impedance matching a signal generator to a plurality of elements of a multi-element load, comprising:an outer conductor having an inner surface; an inner conductor positioned within the outer conductor, and having an outer surface; a first set of transformation sections for impedance matching a first impedance of the signal generator to a second impedance; a second set of transformation sections for matching the second impedance to a third impedance of the plurality of elements of the multi-element load; and wherein each of the first and second sets of transformation sections provides a particular separation distance between the inner surface of the outer conductor and the outer surface of the inner conductor to yield a particular characteristic impedance for each of the first and second sets of transformation sections, thereby substantially matching the first impedance to the third impedance, and wherein each of the first and second sets of transformation sections includes at least one shim disposed along the inner surface of the outer conductor, with each shim yielding the particular characteristic impedance.
