Abstract
A switch device includes a first switch unit, a second switch unit, a first sub-switch unit, a second sub-switch unit, a first resistor and a second resistor. The first switch unit is coupled to a radio-frequency terminal and coupled to the second switch unit in cascode. The first sub-switch unit is coupled to the second sub-switch unit in cascode. The first sub-switch unit is further coupled between control terminals of the first switch unit and the second switch unit. The first sub-switch unit is further coupled to a node between the first resistor and the first switch unit. The second sub-switch unit is further coupled to a node between the second resistor and the second switch unit. When the first switch unit and the second switch unit are transitioned, the first sub-switch unit and the second sub-switch unit can be turned on to discharge and/or neutralize accumulated charges.
