Abstract
Improved switched multiplexer architecture for supporting carrier aggregation in front-end applications. Front end architectures are disclosed that use two filters for a particular frequency band to allow for carrier aggregation using bands that at least partially overlap in frequency. An antenna switch module can be used to independently couple individual filters to an antenna to support a variety of carrier aggregation modes. Switches that connect to the two filters that split the particular frequency band can be configured to operate independently so as to only pass signals within a sub-band of the particular frequency band when operating in certain carrier aggregation modes.
