    Abstract: Embodiments of this disclosure may include a receiver with a reconfigurable processing path for different signal conditions. Such a receiver may reconfigure between a mixer-first configuration and an amplifier-first configuration. In the mixer-first configuration, an RF input signal is not passed through an LNA for amplification before processing the RF input signal for downconversion to baseband and eventual extraction of the information in the signal. In the amplifier-first configuration, an RF input signal is passed through an LNA for amplification before processing the RF input signal for downconversion to baseband and eventual extraction of the information in the signal. Reconfiguring the receiver between mixer-first and amplifier-first configurations may be performed based on detection of jammer signals and/or measurement of signal-to-noise ratio (SNR).

    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.

    Abstract: Wireless signal processing may be improved by using a configurable baseband filter (BBF) in the receive path of a transceiver. A configurable BBF may accommodate processing of different wireless signals in a single integrated circuit (IC) chip. For example, a single IC may support processing of 5G mmWave RF signals and 5G sub-7 GHz RF signals by reconfiguring the BBF with settings appropriate for the different wireless signals. The reconfiguring of the BBF may include adjusting a bandwidth of the BBF and/or adjusting a filter order of the BBF. The reconfiguring of the BBF may be performed in response to detection of jammer signals to improve rejection of the jammer signals.
