ABSTRACT:
A test apparatus has a fixture with upstanding walls and a receiving slot for receiving a substrate holder with a substrate mounted on the holder. Two launchers extend into the receiving slot. Each launcher has two outside contacts and a center pin contact. The pin is electrically insulated from the outside contacts. The center pins contact the two sides of the narrow, central transmission line contact of the substrate, and the two outside contacts of each launcher contact the wider grounded region on the sides of the narrow active region of the substrate. The outside contacts are mounted on a coplanar sleeve that can rotate to some degree so that when the substrate contacts the outside contacts, the coplanar sleeve can rotate so that the surfaces of the electrical contacts against the substrate conform to the surface of the substrate. The holder has two portions. A guide forces the holder to be inserted into the receiving slot such that the substrate does not contact the launcher. The bottom portion of the holder wedges the part of the holder that holds the substrate upward when the holder is fully inserted into the receiving slot so that the substrate moves vertically upward against the launchers. A bias block may also be provided, and DC source inputs extend through the bias block to the plane of the substrate to make contact with portions of the substrate. A hole may also extend through the bias block to provide access to the receiving access.
