Abstract
Improved switched multiplexer architecture for supporting carrier aggregation in front-end applications. A method is disclosed for providing a plurality of switchable paths between an assembly of filters and an antenna port. The method includes connecting a first filter of the filter assembly to the antenna port using a first switch of a switching circuit. The method also includes connecting a second filter of the filter assembly to the antenna port using a second switch of the switching circuit, the second switch independently operated from the first switch. The method also includes passing a first frequency range associated with a first transmission frequency range of a first band using the first filter. The method also includes passing a second frequency range associated with a first receive frequency range of the first band and with a second receive frequency range of a second band using the second filter.
