Switching circuits with reduced insertion loss. A first MOS element of a first conductive type is disposed in a substrate of a second conductive type, and comprises a first terminal coupled to an output/input terminal, a second terminal coupled to an antenna element, a control terminal coupled to a control signal, and a bulk terminal coupled to a first voltage through an external resistor. A deep well region of the first conductive type is disposed in the substrate, separating the first MOS element from the substrate.
