MULTIPLEXING ARCHITECTURES FOR WIRELESS APPLICATIONS

Abstract:

Multiplexing architectures for wireless applications are discussed herein. In some embodiments, a front-end architecture can include a first power amplifier having an output coupled to a transmit filter through a path that is substantially free of a switch. The transmit filter can be configured to support a first transmit band or a second transmit band. The front-end architecture can further include a receive filter configured to support at least a first receive band associated with the first transmit band, and a second power amplifier having an output configured to couple to a first duplexer or a second duplexer through a selector switch. The first duplexer can include a receive portion configured to support a second receive band associated with the second transmit band.
