Design and modeling of back gated graphene based RF switch with CPW transmission line on a high resistivity silicon substrate

This paper presents a design of transmission line based RF switch with graphene. The on-off states of the switch can be adjusted electrically due to the unique properties of monolayer graphene. The transmission between two ports varies more than 30dB when voltage changes from 0 to 30 V. The RF switch provides enough insertion loss and good isolation in on and off states.
