    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: Filters include first through fourth resonant cavities, an input that extends into the first resonant cavity, and an output that extends from the fourth resonant cavity. The first resonant cavity is configured to couple with the second and third resonant cavities, the second resonant cavity is configured to couple with the third and fourth resonant cavities, and the third resonant cavity is configured to couple with the fourth resonant cavity. A magnitude of the coupling between the first and third resonant cavities is configured to be substantially equal to a second magnitude of the coupling between the second and fourth resonant cavities. Combiners that include such filters are also provided.

    Abstract: For wireless cellular communications, a "smart" multi-band combiner system has a multi-band combiner and a passive inter-modulation (PIM) detection sub-system. The multi-band combiner combines multiple transmit signals in different downlink frequency bands into a single, multi-band transmit signal for transmission from a cell tower antenna. The PIM detection sub-system characterizes the frequency components in the multi-band transmit signal to predict PIM products and determine if any predicted PIM products might interfere with any receive signals in any uplink frequency bands. If so, the PIM detection sub-system generates a signal indicating the presence of such predicted interfering PIM products, and the system installer and/or the network administrator can take remedial action to prevent the PIM products from interfering with user communications.

    Abstract: A bandpass filter has a combline structure having a plurality of cascaded nodes (503, 504, 506, 508 ). A plurality of nodes in the filter are connected both to resonant elements ( 514, 517 ) (a.k.a. resonators) and non-resonant elements ( 601, 604 ) (including elements having inductances and/or capacitances that do not resonate in a predetermined frequency band of interest). The resonant frequencies of the resonant elements may be adjusted, in order to adjust the location of the center frequency and/or the width of the passband of the filter. The characteristics of the resonant and non-resonant elements are selected such that the poles of the filter, when plotted on the complex plane, move substantially along the imaginary axis when the resonant frequencies are adjusted, without substantial movement along the real axis. The resulting bandpass filter has substantially constant losses and substantially constant absolute selectivity over a relatively wide range of bandwidths.
