Abstract:
An RF switch device includes transistors coupled in series to form a current path; a drain-source resistive bias network coupled to a drain and a source of each transistor; and a discharge switch coupled between a gate of at least one transistor and the drain-source resistive bias network, wherein the discharge switch establishes a current path between the gate of the at least one transistor and the drain-source resistive bias network only during a switching transient of the RF switch device.
