Abstract:
A radio frequency switch having an N number of switch cells coupled in series is disclosed. Each of the switch cells includes a field-effect transistor (FET), wherein a source of switch cell 1 is coupled to a first port, a drain of switch cell N is coupled to a second port, and a drain of switch cell X is coupled to a source of switch cell X+1 for switch cell 1 through switch cell N. A first diode stack has a first anode coupled to the body of switch cell X and a first cathode coupled to a drain of switch cell X+1 for switch cell 1 through switch cell N−1, and a second diode stack has a second anode coupled to the body of switch cell X and a second cathode coupled to the source of switch cell X−1 for switch cell 2 through switch cell N.
