Abstract

A planar transmission line for use as an attenuator or switch is formed on a semiconductor substrate consisting of a high resistivity semiconductor material 10 and a thin, conductive semiconductor layer 12. Metal conductors 14 and 16 are formed on the conductive semiconductor layer 12 to form the transmission line and at least one of the metal conductors forms a Schottky junction with the layer 12. The gap 18 between the metal conductors 14 and 16 defines a shunt current path through the layer 12. By applying a bias voltage to the metal conductor in the Schottky junction, the conductivity of the shunt path can be controlled by changing the depletion layer width across the Schottky junction. A plurality of planar transmission lines can be combined into multi-port networks, examples of which are cross-bar switching devices and beta element switching devices. <IMAGE>
