Abstract: An amplifier may include multiple stages, with the multiple stages arranged in a fan-out configuration. The fan-out configuration provides multiple amplified signals at multiple amplifier output nodes, which may be coupled to a shared set of downconverters. The shared downconverters may support processing of only a smaller bandwidth than the largest possible bandwidth of an input RF signal input to the amplifier. For example, the downconverters may support a bandwidth matching a smallest bandwidth of a supported RF signal. For example, when the amplifier is intended to support 5G mmWave RF signals and 5G sub-6 GHz RF signals, the downconverters may each individually support a bandwidth of carriers in the 5G sub-6 GHz RF signals but not individually support the entire bandwidth of a possible 5G mmWave RF signal.
