APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING MULTIPLE RADIO SIGNALS OVER A SINGLE ANTENNA
First Claim
1. An apparatus for transmitting and receiving multiple radio frequencies simultaneously over a single antenna, the apparatus comprising:
- a transmitter signal combining apparatus configured to communicatively couple with a plurality of transmitters, wherein the transmitter signal combining apparatus is configured to output a transmission signal based on any signals received from the plurality of transmitters;
at least one transmit/receive signal duplexer coupled to the transmitter signal combining apparatus and configured to provide the transmission signal to an antenna, wherein the antenna receives an incoming radio frequency (RF) signal;
a signal separation apparatus coupled to the at least one transmit/receive signal duplexer and configured to receive the incoming RF signal and provide the incoming RF signal to at least one receiver; and
wherein the at least one transmit/receive signal duplexer is further configured to provide the incoming RF signal to the signal separation apparatus, and limit a direct coupling of the transmission signal into the signal separation apparatus.

Abstract
An apparatus for transmitting and receiving multiple radio frequencies simultaneously over a single antenna is provided. The apparatus comprises a transmitter signal combining apparatus configured to communicatively couple with a plurality of transmitters, wherein the transmitter signal combining apparatus is configured to output a transmission signal based on any signals received from the plurality of transmitters. The apparatus also includes at least one transmit/receive signal duplexer coupled to the transmitter signal combining apparatus and configured to provide the transmission signal to an antenna, wherein the antenna receives an incoming radio frequency (RF) signal. Additionally, the apparatus includes a signal separation apparatus coupled to the at least one transmit/receive signal duplexer and configured to receive the incoming RF signal and provide the incoming RF signal to at least one receiver. Wherein the at least one transmit/receive signal duplexer is further configured to provide the incoming RF signal to the signal separation apparatus, and limit a direct coupling of the transmission signal into the signal separation apparatus.
