A system for transceiving radio frequency signals is provided. The system includes a multiplexing apparatus at a base of a tower and communicatively coupled to a cable, and a low noise amplifier at the base of the tower. The multiplexing apparatus includes a transmitter path, a portion of a receiver path, and a transceiver path portion. The low noise amplifier is operable to amplify signals in a first spectral region and is communicatively coupled to the multiplexing apparatus. The multiplexing apparatus is configured to pass signals in the first spectral region between the cable and a first-band base transceiver station via the low noise amplifier. The multiplexing apparatus is further configured to pass signals in a second spectral region between the cable and at least one second-band base transceiver station.

Multiplexing apparatus in a transceiver system

A multiplexing apparatus comprising at least one band pass filter, a receiver filter, and a transmitter filter is disclosed. The receiver filter, the transmitter filter and each band pass filter are communicatively coupled to a cable so that the receiver filter is configured to pass signals in a first spectral region from the cable to a first-band base transceiver station, the transmitter filter is configured to pass signals in the first spectral region from the first-band base transceiver station to the cable, and each band pass filter is configured to filter and bi-directionally pass signals in a second spectral region between the cable and at least one other base transceiver station.
