Abstract

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.

Claims (15)

1. A multiplexing apparatus, comprising:

a band pass filter portion, each band pass filter in the band pass filter portion communicatively coupled to a cable;

a receiver filter communicatively coupled to the cable;

a transmitter filter communicatively coupled to the cable,

wherein the receiver filter is configured to pass signals in a first spectral region from the cable to a first-band base transceiver station,

wherein the transmitter filter is configured to pass signals in the first spectral region from the first-band base transceiver station to the cable,

wherein 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.

2. The multiplexing apparatus of claim 1 , wherein the receiver filter in the multiplexing apparatus is communicatively coupled to a low noise amplifier.

3. The multiplexing apparatus of claim 2 , wherein the receiver filter is a first receiver filter and wherein the low noise amplifier is operably positioned between the first receiver filter and a second receiver filter, wherein a receiver path for the first spectral region comprises the first receiver filter, the low noise amplifier, and the second receiver filter.

4. The multiplexing apparatus of claim 1 , wherein a transmitter path for the first spectral region comprises the transmitter filter.

5. The multiplexing apparatus of claim 1 , wherein transceiver paths for signals in respective portions of the second spectral region each comprise a respective one of the band pass filters.

6. The multiplexing apparatus of claim 1 , wherein the band pass filter portion comprises a single band pass filter, wherein the cable is a radio frequency cable communicatively coupling the multiplexing apparatus to a diplexer, wherein the diplexer is communicatively coupled to a first antenna and a second antenna, the first antenna configured to receive and transmit signals in the first spectral region and the second antenna configured to receive and transmit signals in the second spectral region.

7. The multiplexing apparatus of claim 1 , wherein the band pass filter portion includes at least two band pass filters, and wherein the cable is a radio frequency cable communicatively coupling the multiplexing apparatus to a multiplexer, wherein the multiplexer is communicatively coupled to a first antenna and at least two other antennae, wherein the first antenna receives and transmits signals in the first spectral region and the at least two other antennae receive and transmit signals in respective portions of the second spectral region.

8. The multiplexing apparatus of claim 1 , wherein at least one band pass filter is an inline cavity filter.

9. The multiplexing apparatus of claim 1 , wherein the low noise amplifier is a ground mounted amplifier.
