1. A wireless communication device including a radio-frequency (RF) module connectable to a base-band (BB) module, the RF module including:

  • at least one transmit antenna;

    a plurality of receive antennas;

    at least one uplink input connectable to the BB module to receive from the BB module uplink signals to be transmitted via the at least one transmit antenna;

    a plurality of downlink outputs connectable to the BB module to provide the BB module with downlink signals corresponding to wireless signals received via the plurality of receive antennas; and

    a control interface connectable to the BB module to receive from the BB module a filter-calibration control signal,wherein, responsive to the filter-calibration control signal, the RF module is to output via one or more of the plurality of downlink outputs one or more respective filtered calibration signals corresponding to a filter calibration signal received via the uplink input.
