Patent number: 11973522Abstract: Aspects of this disclosure relate to a front end architecture for selectively adding an external carrier aggregation band. A switch element can connect a radio frequency signal path to an antenna path through a frequency domain multiplexer, such as a diplexer, in a first mode. The switch element can connect the radio frequency path to the antenna path and bypass the frequency domain multiplexer in a second mode. The frequency domain multiplexer can be external to a front end module that include the radio frequency signal path. In the first mode, a front end system can support carrier aggregation with a band associated with circuitry implemented external to the front end module.Type: GrantFiled: March 10, 2021Date of Patent: April 30, 2024Assignee: Skyworks Solutions, Inc.Inventors: Jen-Chien Chang, Reza Kasnavi, Roman Zbigniew Arkiszewski, Jeffrey Gordon Strahler, John G.
