Abstract: Certain aspects of the present disclosure generally relate to techniques and apparatus for operating a wireless receiver of the apparatus in a high linearity mode. An example method includes operating the apparatus in a first mode with transmission of a plurality of transmit signals. The method also includes attenuating a received signal via an attenuator while operating the apparatus in the first mode. The method further includes amplifying the attenuated signal with an amplifier while operating the apparatus in the first mode. For certain aspects, the method further involves operating the apparatus in a second mode, bypassing the attenuator while operating the apparatus in the second mode, and amplifying the received signal with the amplifier while operating the apparatus in the second mode.

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 communication that support reconfiguring degeneration components in a converged RF transceiver supporting carrier aggregation across sub-6 GHz frequency bands and mmWave frequency bands. In a first aspect, an apparatus includes an input port configured to receive a mixer input signal; a first mixer forming at least a portion of an HRM mixer and coupled to the input port; a first configurable degeneration component of a first processing path coupled between the input port and the first mixer; and a controller coupled to the first degeneration component, wherein the controller is configured to control a first aspect of a first degeneration component. Other aspects and features are also claimed and described.

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: The disclosure relates to an apparatus including a receiver configured to process a radio frequency (RF) signal to generate a baseband signal; a radio frequency (RF) jammer detector configured to generate a signal indicative of whether an RF jammer is present at an input of the receiver; and a receiver bias circuit configured to generate a supply voltage for the receiver based on the RF jammer indication signal. In another aspect, the apparatus includes constant gain bias circuit to maintain the gain of the receiver constant in response to changes in the supply voltage. In other aspects, the receiver bias circuit may suspend the generating of the supply voltage based on the RF jammer indication signal if the power level of the target received signal is above a threshold. In other aspects, the receiver bias circuit changes the supply voltage during cyclic prefix (CP) intervals between downlink intervals.
