Claim:
1. A method for operating a radio-frequency switch, the method comprising: controlling a field-effect transistor disposed between a first node and a second node so that the field-effect transistor is in an ON state or an OFF state, the field-effect transistor having a drain, a source, a body and a gate; and discharging interface charge from the body of the field-effect transistor through a coupling path connected between the body and the gate, the coupling path being electrically isolated from the drain and the source and including a resistor and a capacitor connected in series, such that the capacitor of the coupling path blocks any and all DC current flow from the gate to the body and from the body to the gate, the resistor being connected directly to the gate at a first end and to the capacitor at a second end.
