Abstract
Aspects of the present disclosure relate to a packaged module with a radio frequency isolation structure that includes a racetrack, a conductive layer, and a conductive feature in an electrical path between the racetrack and the conductive layer. The racetrack can be disposed in a substrate and configured at a ground potential. The racetrack can include a break.

(canceled)
A packaged module comprising:
- a substrate having a major surface;
- a radio frequency component coupled to the major surface of the substrate;
- and
- a radio frequency isolation structure including a racetrack in the substrate, a conductive layer positioned such that the radio frequency component is located between the conductive layer and the major surface of the substrate, and a conductive feature in an electrical path between the racetrack and the conductive layer, the racetrack configured at a ground potential and disposed around the radio frequency component, and the racetrack having a break.
