Abstract:
An RF switch device includes transistors coupled in series forming an RF conductive current path; a first resistive bias network forming a DC conductive bias path between gate nodes of the plurality of transistors; and a first ESD bias component coupled between the RF conductive current path and the first resistive bias network, wherein the first ESD bias component provides a DC conductive path between the RF conductive current path of the RF switch device and the first resistive bias network during an ESD event.
