    Abstract: PROBLEM TO BE SOLVED: To provide an improved power amplifier system with redundancy. SOLUTION: An antenna system is mounted with a divider, that receives a divider input signal and produces divider output signals. Amplifiers receiver corresponding divider output signals and generate respective amplified outputs. A coupler converts the amplified outputs into an antenna signal. An antenna receives the antenna signal and transmits it. The power of the antenna signal is a function of number of amplified outputs which communicate with the coupler.

    Abstract: PROBLEM TO BE SOLVED: To eliminate insertion loss due to physical connection of transmission lines from many base stations at a common connection point by preventing interference by sufficiently separating frequency bandwidths allocated to different radio system. SOLUTION: In the system and method for effectively connecting communications of base stations of many radio system, in an embodiment, a radio system combiner servers as an interface between base stations of 1st and 2nd radio systems ('1st base station' and '2nd base station') and a common antenna to greatly remove spurious noise from the 1st base station at the frequency allocated to the 2nd base station to prevent the transmitting electric power from the 1st base station from being sent to a receiving circuit of the 2nd base station in the common antenna constitution. The combiner includes a 1st combiner filter between a duplexer of the 1st base station and a common connection point and a 2nd combiner filter between a duplexer of the 2nd base station and the common connection point.

    Abstract: An antenna system (10) includes a splitter (34), which receives a splitter input signal (28) and produces a plurality of splitter output signals (36). A plurality of amplifiers (46) receive respective ones of the splitter output signals and produce respective amplified outputs. A combiner (56) transforms a plurality of the amplified outputs to an antenna signal. An antenna (22) receives and transmits the antenna signal. A power of the antenna signal is a function of a number of the amplified outputs communicating with the combiner.

    Abstract: A system and method effectively combines communications of the base stations (110,130) of multiple wireless systems on the same antenna structure (180). In one implementation, a wireless system combiner (150) serves as an interface between base stations (110,130) of first and second wireless systems ("first base station" and "second base station") and a shared antenna (180) to substantially eliminate spurious noise from the first base station at frequencies allocated to the second base station and prevent transmit power from the first base station from feeding into the reception circuitry of the second base station in a shared antenna configuration. The combiner includes a first combiner filter (154) between a duplexer (116) of the first base station (110) and a common connection point (156) and a second combiner filter (152) between a duplexer (136) of the second base station (130) and the common connection point. The first combiner filter filters out spurious noise generated by first base station transmitter at frequencies outside the frequency band allocated to the first base station, for example using a high Q value band-pass or band-reject filter. The second combiner filters out signal power at frequencies outside the second base station receive band to prevent transmit signal power of the first base station from feeding into the second base station's receiver circuitry, thereby preventing intermodulation.
