A booster system in a cellular phone base station comprises a plurality of power amplifiers, each of which configured to receive a signal provided by a corresponding transceiver unit that is coupled to said booster system. A hybrid combiner is coupled to the power amplifiers, and is configured to combine the signals generated by each of the power amplifiers. A VSWR sensor is configured to sense a voltage standing wave ratio at an output port of the booster system. Furthermore, a radio frequency relay is provided, which is configured to receive signals provided by the transceiver units. The radio frequency relay is triggered in response to an indication signal based on either a failure in the booster system or a failure in the signal path following the booster system.
Broadband Combining System With High Spectrum Efficiency For Use In Wireless Communications
A system for combining a plurality of signals in a wireless communication device employs a plurality of base station duplexers each coupled to a corresponding base station from a plurality of collocated base stations, each base station capable of receiving and transmitting signals in accordance with a corresponding transmission protocol. Each duplexer includes a transmit and receive paths for allowing signals to be transmitted from the base station and further allowing signals to be received by the base station. Isolators are each coupled to a corresponding one of the transmit path of each of the duplexers. Bandpass filters are each coupled to an output port of a corresponding one of the isolator and a combiner receives signals provided by each one of the band pass filters. An antenna duplexer is coupled to an output port of the combiner via a transmit path, where the duplexer provides a combined signal of the collocated base stations to an antenna. The duplexer further includes a receive path for providing signals received by the antenna to a corresponding receive path of each of the base station duplexers.
