Abstract

A circuit package includes first and second units containing functional circuitry. At least one RF isolation link interconnects the first and second units and provides voltage isolation between the first and second units. The RF isolation link provides data between the first unit and the second unit using an RF carrier signal that sweeps between a first frequency and a second frequency.
