Abstract
Some demonstrative embodiments include interfacing between BB and RF modules of a wireless communication device. In some embodiments the RF module includes 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. The RF module may 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. Other embodiments are described and claimed.
