Abstract: Carrier aggregation (CA) may cause interference between operation on two or more carriers within a user equipment (UE). This interference can degrade signal quality on one or more of the carriers involved in the carrier aggregation, which may be referred to as "desensing" one or more carriers. One or more isolating buffers may be coupled at a down-conversion mixer at a point where the down-conversion mixer receives a signal from a transmission line for isolating the transmission line from other transmission lines. The isolating buffer may reduce the effect of interference between multiple transmission lines carrying different carriers during carrier aggregation (CA) operation. The isolating buffers may be used in an RF transceiver supporting both 5G sub-7 GHz and 5G mmWave wireless networks and carrier aggregation across sub-7 GHz and mmWave bands.

Abstract: A reconfigurable filter circuit has a first path including a transimpedance amplifier (TIA). The transimpedance amplifier has an input that receives an input current and an output that outputs a voltage. The reconfigurable filter circuit also includes a switchable feedback path. The switchable feedback path includes a first low-pass filter coupled to an output of the TIA. The switchable feedback path also includes a first switch to couple the feedback path to provide a feedback current to the first path resulting in a bandpass response in the output voltage when the switch is closed and a low-pass response in the output voltage when the switch is open.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for dynamically adjusting a voltage-controlled oscillator (VCO) frequency, a local oscillator (LO) divider ratio, and/or a receive path when adding or discontinuing reception of a component carrier (CC) in a carrier aggregation (CA) scheme. This dynamic adjustment is utilized to avoid (or at least reduce) VCO, LO, and transmit signal coupling issues with multiple component carriers, with minimal (or at least reduced) current consumption by the VCO and the LO divider.

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.
