Patent ID: 8022795

Claim:
An adapter for connecting a pair of transmission lines in a system having a nominal value of characteristic impedance, each of the transmission lines in electrical communication to a component in the system, the adapter comprising: a center conductor having a longitudinal axis; a first elongated section in surrounding relation to the center conductor; a second elongated section insertably engaging the first elongated section along the longitudinal axis; and a plurality of tuning elements disposed in a spaced relationship on a portion of the center conductor and having a volumetric shape with a width W, at least one of the tuning elements having a plurality of positions on the center conductor including a first position and a second position that is different than the first position, the second position corresponding to a value for the spaced relationship that is less than the sum of the width W of each of the tuning elements; wherein relative movement between the first elongated section and the second elongated section causes the first position to change to the second position.
