1. A radio-frequency switch comprising:

  • a first field-effect transistor disposed between first and second nodes, the first field-effect transistor having a body and a gate;

    a coupling circuit that couples the body and the gate of the first field-effect transistor, the coupling circuit including a second field-effect transistor connected in series with a first resistor; and

    an adjustable-resistance circuit connected to the body of the first field-effect transistor, the adjustable-resistance circuit including a second resistor in series with a parallel combination of a third resistor and a bypass switch.
