Abstract
A radio frequency switch circuit includes a series circuit. The series circuit includes a first series connection group and a second series connection group. The first series connection group includes a plurality of first transistors. The second series connection group includes a plurality of second transistors. Control terminals of the first transistors are all coupled to a first control node. Control terminals of the second transistors are all coupled to a second control node. When an electrostatic discharge event occurs, a voltage at the first control node is different from a voltage at the second control node. In a normal operation state, a switch state of the first series connection group and a switch state of the second series connection group are the same as each other.
