Publication number: 20230131326Abstract: A surface mount device inductor has a package casing sized to attenuate electromagnetic coupling between the inductor coils of the surface mount device inductors. The surface mount device inductor includes an inductor coil, an anode structure disposed over a first end of the inductor coil and a cathode structure disposed over a second end of the inductor coil opposite the first end, the cathode structure being spaced apart from the anode structure. One or both of the anode structure and the cathode structure comprise a shield portion disposed at least partially over the inductor coil to thereby reduce electromagnetic coupling between adjacent surface mount device inductors. The package casing makes the surface mount device inductors self-shielding. The surface mount device inductors can be incorporated into a radiofrequency module, and can be incorporated into a front end system of a wireless mobile device.Type: ApplicationFiled: December 23, 2022Publication date: April 27, 2023Inventors: John C. Baldwin, Weimin Sun

Patent number: 10727893Abstract: Reconfigurable front-end module for carrier aggregation. In some embodiments, a front-end module can include a plurality of signal ports and a plurality of antenna ports. The front-end module can further include a switch assembly configured to route signals along one or more of a plurality of filtering paths between the signal ports and the antenna ports. Each of the filtering paths can include a filter, and the filtering paths can be configured to allow the antenna ports to be combined outside of the front-end module to accommodate a corresponding antenna configuration. The filtering paths can be further configured to maintain desirable filtering performance levels for different combinations of the antenna ports outside of the front-end module corresponding to the different antenna configurations.Type: GrantFiled: April 16, 2018Date of Patent: July 28, 2020Assignee: Skyworks Solutions, Inc.Inventors: Yaxing Zhang, Shaun Bryce Chamberlain, Srivatsan Jayaraman, Ethan Chang, Roman Zbigniew Arkiszewski, Reza Kasnavi, John C.
