A method modifies dual gate transistor into a radio frequency switch. The method attaches a first signal input to a first gate of the transistor, attaches a second signal input to the source or drain of the transistor, attaches a common gate contact to the first gate and the second gate, attaches a signal output to a second gate of the transistor, attaches a source/drain contact connected to the source region or drain region where the second signal input is attached, and modulates the voltage supplied to the common gate and the source/drain contact to control the radio frequency switch.
