A device (24) that communicatively couples a number of transmitters and receivers (18) to a number of antennas (28). The device includes transmit ports (TX1, TX2, TX3, TX4) each of which may be connected to a respective transmitter, receive ports (RA1, RA2, RA3, RA4) each of which may be connected to a respective receiver, and antenna ports (ANT1, ANT2, ANT3, ANT4) each of which may be connected to a respective antenna. One coupling unit (32, 34, 68) has inputs connected to each transmit port and outputs to respective antenna ports for combining individual transmit signals received at each transmit port to form a combined transmit signal, and outputs the combined transmit signal to each respective antenna port. A second coupling unit (52, 56, 68, 64, 66) has inputs connected to respective antenna ports and outputs to each receive port for combining individual receive signals from each respective antenna port to form a combined receive signal, and outputs the combined receive signal to the receive ports.
