ABSTRACT:
A device that communicatively couples a number of transmitters and receivers to a number of antennas. The device includes transmit ports each of which may be connected to a respective transmitter, receive ports each of which may be connected to a respective receiver, and antenna ports each of which may be connected to a respective antenna. One coupling unit 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 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.
