Abstract
A RF switch circuit includes a voltage divider circuit and a semiconductor device. The semiconductor device has an activated state and a deactivated state. The voltage divider circuit has an input terminal connected to a first line and an output terminal connected to a second line. The first line is connected to a power source. A gate terminal of the semiconductor device is connected to the second line. In the activated state, a source terminal and a drain terminal of the semiconductor device are each selectively connected to ground. In the deactivated state, the source terminal and the drain terminal of the semiconductor device are each selectively connected to the power source.
