Patent attributes
Described herein are systems configured for carrier aggregation. Systems include a multiplexing circuit having a filter assembly, switching circuit with a switching path, and a switchable impedance. The filters can be designed so that when operated simultaneously (e.g., during multi-band operation) the same inductance can be used allowing the switching network to switch in a particular inductance into the path. The described systems can include an inductance that is coupled to an output port so that when operating in single-band mode, the different paths share the same inductance. Relative to other solutions, the described systems can improve performance (e.g., reduce insertion loss), reduce the number of components in the associated module, reduce manufacturing costs, and the like.
