Patent ID: 8514008

Claim:
An apparatus comprising: a main N-channel transistor having a first terminal, a second terminal, and a gate terminal and configured for passing a Radio Frequency (RF) signal; a first turn-off N-channel transistor having a first terminal, a second terminal, and a gate terminal, wherein the second terminal of the first turn-off N-channel transistor is coupled to the gate terminal of the main N-channel transistor; a second turn-off N-channel transistor having a first terminal, a second terminal, and a gate terminal, wherein the second terminal of the second turn-off N-channel transistor is coupled to the first terminal of the first turn-off N-channel transistor, and wherein the first terminal of the second turn-off N-channel transistor is coupled to the first terminal of the main N-channel transistor; and a first control conductor, wherein the main transistor is turned off when a first digital control signal on the first control conductor has a first digital logic value, and wherein the main transistor is turned on when the first digital control signal on the first control conductor has a second digital logic value opposite the first digital logic value.
