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: 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.

Abstract: This disclosure provides systems, methods, and devices for wireless communications that support multiple subscriber identity module (MSIM) operation. In a first aspect, an apparatus for wireless communications includes an input port for receiving a radio frequency (RF) signal comprising a first carrier corresponding to a first subscriber identity module (SIM) and a second carrier corresponding to a second subscriber identity module (SIM); and a split low noise amplifier (LNA) coupled to the input port and a first output port and a second output port, the split LNA configured to output the RF signal with a first gain as a first amplified RF signal at the first output port and to output the RF signal with a different, second gain as a second amplified RF signal at the second output port. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods, and devices for wireless communications that support downconversion in a radio frequency (RF) system. In a first aspect, an apparatus for wireless communications includes a first mixer coupled to an input node; a second mixer coupled to the input node; and a first mixer bias circuit configured to output a first local oscillator (LO) signal, the first mixer bias circuit coupled to the first mixer and to the second mixer to output the first LO signal to the first mixer and to the second mixer. Other aspects and features are also claimed and described.
