Abstract

Improved Radio Frequency (RF) switches are provided herein. According to one aspect, an RF switch comprises one or more stages. In one embodiment, each stage comprises a signal input terminal, a signal output terminal, a control input terminal, and a switching device having a source connected to the signal input terminal, a drain connected to the signal output terminal, a gate for controlling the on/off state of the switching device, and a body terminal. Each stage includes a gate resistor connected in series between the control input terminal and the gate and a rectification circuit for rectifying a voltage across the source and drain to provide a local bias voltage to the body terminal.
