Abstract
A switch circuit is provided that includes at least one main switching device and at least one shunt switching device. Each main switching device is connected in series with a conductor that carries an RF signal between an input circuit and an output circuit. Each shunt switching device is connected between a controlling terminal of the main switching device and a high frequency ground. The switch circuit can provide substantially improved OFF state isolation over other approaches.
