Abstract
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.
