Abstract

In accordance with an embodiment, a radio frequency (RF) switching circuit includes a plurality of series connected RF switch cells comprising a load path and a control node, a plurality of first gate resistors coupled between control nodes of adjacent RF switch cells, and an input resistor having a first end coupled to a control node of one of the plurality of RF switch cells and a second end configured to an output of a switch driver. Each of the plurality of series connected RF switch cells includes a switch transistor.
