Patent number: 8803531Abstract: A method and arrangement for facilitating through-line mismatch RF testing using an air-isolated coaxial line having an inner conductor surrounded by a coaxial shielding. At least one circular opening is provided through the shielding. A radially adjustable piston is provided in each opening such that it is electrically connected to the shielding and such that its protrusion from an inside of the shielding towards the inner conductor is adjustable. The position of the radially adjustable piston is calibrated with a known level of RF mismatch so that a desired level of mismatch can be created through adjustment of the piston. By adjusting the piston so that it does not protrude beyond the inside of the shielding, the arrangement is effectively set to zero and does not have to be disconnected after use.Type: GrantFiled: November 27, 2008Date of Patent: August 12, 2014Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventor: Lars Arvidsson
