Abstract
A device for switching radio frequency signals that includes at least a first MOS transistor for selectively interrupting or transmitting the signals between at least first and second terminals as a function of a control signal. The gate of the first MOS transistor is connected to the first terminal, and both the drain and source of the first MOS transistor are connected to the second terminal. In a preferred embodiment, the first MOS transistor selectively interrupts or transmits the signals between the first terminal and the second terminal, and the device also includes a second MOS transistor for selectively interrupting or transmitting the signals between the first terminal and a third terminal. A system for processing radio frequency signals is also provided. The system includes at least one device for switching radio frequency signals, and the device includes at least a first MOS transistor for selectively interrupting or transmitting the signals between at least first and second terminals of the system as a function of a control signal. The gate of the first MOS transistor is connected to the first terminal, and both the drain and source of the first MOS transistor are conne…
