Wireless communication configurations are disclosed that include a plurality of such front-end modules to support uplink and/or downlink carrier aggregation. Individual front end modules include a power amplifier module to amplify signals received at a transceiver port and an envelope tracker to increase efficiency of the power amplifier module. The front-end modules include a multiplexer and an antenna switch module with a plurality of duplexers between them along a corresponding plurality of paths. One path includes a first duplexer configured to process frequency division duplex (FDD) signals and another path includes a second duplexer configured to process time division duplex (TDD) signals. The front-end modules also include a low noise amplifier module coupled to the second duplexer to amplify TDD signals while received FDD signals are directed off module for amplification."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Front-end modules for carrier aggregation","description":"Disclosed herein are front-end modules that support carrier aggregation.
