Claim:
1. An apparatus comprising: a balun circuit including an input coil and an output coil disposed on an integrated circuit die; a first bond wire coupled to a first terminal of the balun circuit through a first die pad and coupled to a first output terminal of an integrated circuit package housing the integrated circuit die; a second bond wire coupled to a second terminal of the balun circuit through a second die pad and coupled to a second output terminal on the integrated circuit package, the second output terminal for coupling to a first ground, the first ground being a board ground of a printed circuit board on which the integrated circuit package is mounted; and a third bond wire coupled to the second output terminal and to an electrostatic discharge (ESD) circuit on the integrated circuit die through a third die pad, wherein the ESD circuit is coupled to a second ground, the second ground being an integrated circuit ground on the integrated circuit die; and wherein voltage swings on the first and second bond wires are approximately an order of magnitude greater than a voltage swing at the third die pad.
