Abstract
Aspects of the present disclosure relate to determining a layout of a racetrack that forms part of an RF isolation structure of a packaged module and the resulting RF isolation structures. Locations of where the racetrack can be adjusted (for example, narrowed) and/or removed without significantly degrading the EMI performance of the RF isolation structure can be identified. In certain embodiments, a portion of the racetrack can be removed to create a break and/or a portion of the racetrack can be narrowed in a selected area.

2. A method of determining a racetrack layout, the method comprising:
-
obtaining electromagnetic interference data for a module, the electromagnetic interference data being associated with an electromagnetic probe; identifying an area of the module that is less sensitive to external radiation than another area of the module based on the electromagnetic interference data, the module including a radio frequency component coupled to a major surface of a substrate; and determining a racetrack layout based on said identifying, the racetrack being disposed such that the major surface of the substrate is between the racetrack and the radio frequency component, the racetrack and a conductive layer forming a portion of a radio frequency isolation structure around the radio frequency component, and the radio frequency component being disposed between the conductive layer and the major surface of the substrate. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A method of determining a racetrack layout, the method comprising:
-
performing an electromagnetic probe to obtain electromagnetic interference data for a module; identifying an area of the module that is less sensitive to external radiation than another area of the module based on the electromagnetic interference data, the module including a radio frequency component coupled to a major surface of a substrate; and determining a racetrack layout based on said identifying, the racetrack being disposed such that the major surface of the substrate is between the racetrack and the radio frequency component, the racetrack layout having at least one of a break or a narrowed section in the area of the module that is less sensitive to external radiation, the racetrack and a conductive layer forming a portion of a radio frequency isolation structure around the radio frequency component, and the radio frequency component being disposed between the conductive layer and the major surface of the substrate. - View Dependent Claims (16, 17, 18)
