1. A method comprising:
- applying a gate control voltage to a gate of a switch transistor in an RF circuit;
applying a body control voltage to a body of the switch transistor, wherein the body control voltage is a positive bias voltage when the switch transistor is in an on state;
wherein the gate control voltage is applied from a first voltage control source to the gate; and
wherein the body control voltage is applied from a second voltage control source to the body, further wherein the second voltage control source is independent from the first voltage control source.

Abstract
In some method and apparatus embodiments, an RF circuit comprises a switch transistor having a source, a drain, a gate, and a body. A gate control voltage is applied to the gate of the switch transistor. A body control voltage is applied to the body of the switch transistor. The body control voltage is a positive bias voltage when the switch transistor is in an on state. In some embodiments, an RF circuit comprises a control voltage applied to the gate of the switch transistor through a first resistance and applied to the body of the switch transistor through a second resistance. The first resistance is different from the second resistance.
