Publication number: 20220254730Abstract: Signal isolation for module with ball grid array. In some embodiments, a packaged module can include a packaging substrate having an underside, and an arrangement of conductive features implemented on the underside of the packaging substrate to allow the packaged module to be capable of being mounted on a circuit board. The arrangement of conductive features can include a signal feature implemented at a first region and configured for passing of a signal, and one or more shielding features placed at a selected location relative to the signal feature to provide an enhanced isolation between the signal feature and a second region of the underside of the packaging substrate.Type: ApplicationFiled: January 24, 2022Publication date: August 11, 2022Inventors: Howard E. CHEN, David VIVEIROS, JR., Russ Alan REISNER, Robert Francis DARVEAUX

Patent number: 10623046Abstract: In an embodiment, an apparatus includes a first radio frequency (RF) signal path and a second RF signal path. The first RF signal path can provide a first RF signal when active and the second RF signal path can provide a second RF signal when active. The second RF signal path can include a matching network with a load impedance configured to prevent a resonance in the second RF signal path due to coupling with the first RF signal path when the first RF signal path is active.Type: GrantFiled: January 15, 2019Date of Patent: April 14, 2020Assignee: Skyworks Solutions, Inc.Inventors: Weimin Sun, David Viveiros, Jr., Russ Alan Reisner
