1. An integrated circuit package, comprising:
- an encapsulation; and
a lead frame, a portion of the lead frame disposed within the encapsulation, the lead frame comprising;
a first conductor forming a first conductive loop disposed substantially within the encapsulation;
a second conductor galvanically isolated from the first conductor, wherein the second conductor forms a second conductive loop disposed substantially within the encapsulation proximate to and magnetically coupled to the first conductive loop to provide a communication link between the first and second conductors;
a first bond wire disposed within the encapsulation and coupling together portions of the first conductive loop.

Abstract
An integrated circuit package includes an encapsulation and a lead frame. A portion of the lead frame is disposed within encapsulation. The lead frame includes a first conductor having a first conductive loop disposed substantially within the encapsulation. The lead frame also includes a second conductor that is galvanically isolated from the first conductor. The second conductor includes a second conductive loop that is substantially disposed within the encapsulation proximate to and magnetically coupled to the first conductive loop to provide a communication link between the first and second conductors.
