Abstract: The invention is a compact three-port signal combiner suitable for use in a base station having two different wireless systems. The combiner is designed as a four-port network, but one of the ports is terminated with a predetermined load, thus leaving three ports for connection to user equipment. A first port (A) receives from an antenna a first input signal comprising first and second receive bands and transmits to the antenna a first output signal comprising a transmit band. A second port (R), connected to the first wireless system, outputs to the first wireless system a second output signal comprising the first and second receive bands. A third port (T\R) outputs, to the second wireless system, a third output signal comprising the first and second receive bands and receives from the second wireless system a second input signal that is to be transmitted from the first port.

Abstract: In-line filters may include a tubular metallic housing defining a single inner cavity that extends along a longitudinal axis and a plurality of resonators that are spaced apart along the longitudinal axis within the single inner cavity, each resonator having a stalk. The stalks of first and second of the resonators that are adjacent each other are rotated to have different angular orientations.

Abstract: Filters include a housing and at least first through fourth resonators are mounted within the housing. The first resonator is configured to couple with the second resonator and the third resonator but not the fourth resonator. The second resonator is configured to couple with the first resonator and the fourth resonator but not the third resonator. The third resonator is configured to couple with the first resonator and the fourth resonator but not the second resonator. The fourth resonator is configured to couple with the second resonator and the third resonator but not the first resonator. The first, second and fourth resonators are configured to resonate within a passband of the filter, while the third resonator is configured to resonate outside the passband of the filter.

Abstract: An in-line resonator filter has a linear array of three or more conductors. A first pair of adjacent conductors has inductive main coupling and oppositely signed capacitive main coupling, while a second pair of non-adjacent conductors has inductive cross-coupling. The first and second pairs have one conductor in common. Between the second pair of non-adjacent conductors, there is no direct ohmic connection that provides the corresponding inductive cross-coupling. The oppositely signed capacitive main coupling compensates for at least a portion of the inductive main coupling between the first pair of adjacent conductors. The in-line resonator filter is able to provide one or more transmission zeros without requiring any discrete bypass connectors that provide direct ohmic connection between pairs of non-adjacent conductors. As such, the in-line resonator filters can be smaller, less complex, and less susceptible to damage.
