Abstract
Apparatus suitable for on-wafer probing of microwave integrated circuits includes a coplanar waveguide carried on one surface of an elongate, tapered, dielectric substrate. The waveguide includes a signal conductor extending substantially the length of the substrate and a pair of ground conductors extending along the opposite edges of the signal conductor. The substrate is bonded to a metal mounting block adjacent one end of an coaxial electrical connector. Conductive bonding material, suitably a conductive epoxy material, is applied along the outer edges of the ground conductors to establish a low impedance ground path between the coaxial waveguide and the metal block.
