ABSTRACT:
A switch circuit is disclosed including a first FET device coupled in series with an input terminal and an output terminal. A second FET device coupled to the first device in a shunt configuration. The FET devices operative in a first mode to enable electronic signal transmission between the input and output terminals, and further operative in a second mode to prevent the electronic signal transmission. A biasing network for enabling a single control signal to operate the FET devices in both the first and second modes.
