17. A wireless device comprising:
a first antenna configured to receive a first radio-frequency (RF) signal;
a first front-end module (FEM) in communication with the first antenna, the first FEM including a packaging substrate configured to receive a plurality of components, the first FEM further including a receiving system implemented on the packaging substrate, the receiving system including a plurality of amplifiers, each one of the plurality of amplifiers disposed along a corresponding one of a plurality of paths between an input of the receiving system and an output of the receiving system and configured to amplify a radio-frequency (RF) signal received at the amplifier, an input multiplexer configured to receive one or more RF signals at one or more input multiplexer inputs and to output each of the one or more RF signals to a selected one or more of a plurality of input multiplexer outputs to propagate along a respective one or more of the plurality of paths, an output multiplexer configured to receive one or more amplified RF signals propagating along the respective one or more of the plurality of paths at one or more respective output multiplexer inputs and to output each of the one or more amplified RF signals to a selected one of a plurality of output multiplexer outputs, and a controller configured to receive a band select signal and, based on the band select signal, to control the input multiplexer and the output multiplexer such that, in response to a band select signal indicating that the one or more RF signals includes a single frequency band, the controller is configured to control the output multiplexer to route an amplified RF signal received at an output multiplexer input corresponding to the single frequency band to a default output multiplexer output, the default output multiplexer output being different for different single frequency bands; and
a communications module configured to receive a processed version of the first RF signal from the first FEM via a plurality of transmission lines respectively coupled to the plurality of output multiplexer outputs and to generate data bits based on the processed version of the first RF signal.
