Front-end modules with integrated power amplifiers and low noise amplifiers to support carrier aggregation

Abstract:

Disclosed herein are front-end modules that support carrier aggregation. 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 a low-noise amplifier module to amplify signals received at an antenna port. The front-end modules include a multiplexer and an antenna switch module with a plurality of filters and duplexers between them along a corresponding plurality of paths. One path processes frequency division duplex (FDD) signals and another path processes time division duplex (TDD) signals. The front-end modules amplify TDD signals while received FDD signals are directed off module for amplification.
