Abstract
A test fixture for inverted microcircuits having spaced shelf assemblies h parallel shelves for respectively supporting a substrate for a microcircuit and a substrate for a ground plane in such a manner that the distance between them can be varied while test signals are coupled to the microcircuit via a coaxial cable coupled to a fitting on one shelf assembly and signals are coupled from the microcircuit via a coaxial cable coupled to a fitting on the other shelf assembly to test apparatus for determining the performance of the circuit.
