Abstract: A wireless communication device can include an antenna array configured to receive a plurality of radio frequency (RF) signals, RF circuitry, and digital baseband receive circuitry. The RF circuitry is configured to process the plurality of RF signals received via the antenna array to generate a single RF signal. The digital baseband receive circuitry is coupled to the RF circuitry and is configured to generate a downconverted signal based on the single RF signal, amplify the downconverted signal to generate an amplified downconverted signal, and convert the amplified downconverted signal to generate a digital output signal for processing by a wireless modem. The digital baseband receive circuitry further includes at least a first filtering system configured to filter the downconverted signal prior to amplification.

Abstract: A wireless communication device can include an antenna configured to sense a radio frequency (RF) signal. The wireless communication device can include signal estimation circuitry configured to generate estimates of amplitude and frequency for unmodulated spurs within the RF signal. The wireless communication device can further include multi-tone generator circuitry coupled to the signal estimation circuitry and configured to generate a composite spur cancellation signal based on the estimates of amplitude and frequency for unmodulated spurs within the RF signal. The wireless communication device can further include adder circuitry configured to subtract the spur cancellation signal from the RF signal to generate a spur cancelled signal.

Abstract: An apparatus of user equipment (UE) includes a radio integrated circuit (IC), an adjustable external low noise amplifier (eLNA) external to the radio IC, and processing circuitry. The radio IC includes a receive signal circuit path including an adjustable gain internal low noise amplifier (iLNA), and a transmit signal circuit path including a digital-to-analog converter (DAC) circuit configured to convert digital signals to analog baseband signals for transmitting. The processing circuitry is configured to provide digital values of the digital signals to the DAC circuit and initiate adjusting gain of one or both of the iLNA and the eLNA according to the digital values.
