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.
