Abstract: An amplifier (320) may include multiple stages (322, 324), with the multiple stages (322, 324) 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 (330A, 330B, 330C). The shared downconverters (330A, 330B, 330C) may support processing of only a smaller bandwidth than the largest possible bandwidth of an input RF signal input to the amplifier (320). For example, the downconverters may support a bandwidth matching a smallest bandwidth of a supported RF signal. For example, when the amplifier (320) is intended to support 5G mmWave RF signals and 5G sub-6 GHz RF signals, the downconverters (330A, 330B, 330C) 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.
