1. A radio frequency switch circuit comprising:
a series circuit comprising:
a first series connection group comprising a plurality of first transistors; and
a second series connection group comprising a plurality of second transistors,
wherein control terminals of the first transistors are all coupled to a first control node,
wherein control terminals of the second transistors are all coupled to a second control node,
wherein when an electrostatic discharge event occurs, a voltage at the first control node is different from a voltage at the second control node, and
wherein 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.
