    Abstract: Filters include a housing having an input port and an output port and a plurality of resonant cavities within the housing. Each resonant cavity may include a respective notch resonator. The filter may further include a bandpass filter that includes a plurality of bandpass resonators, the bandpass filter extending between the input port and the output port. The bandpass filter may replace a transmission line that is included in conventional filters.

    Abstract: The present invention provides filter assemblies, tuning elements and a method of tuning a filter. A filter assembly includes a housing having a top cover, a bottom cover and at least one sidewall, the top cover, the bottom cover and the at least one sidewall defining an internal cavity, the housing configured to receive first through third radio frequency (“RF”) transmission lines; a top metal sheet mounted within the internal cavity that has a plurality of openings that form a first hole pattern; and a bottom metal sheet mounted within the internal cavity that has a plurality of openings that form a second hole pattern. The top and bottom metal sheets are vertically spaced-apart from each other in a vertically stacked relationship within the internal cavity. The top metal sheet and the bottom metal sheet each include at least one resonator.

    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: The present invention provides target devices such as filter units with at least one receiving channel with a stop surface that is electrically conductive and at least one cable with a connector assembly on a first end portion. The connector assembly includes a first member with an open channel. The first member is coupled to the end portion of the outer conductor with the free end of the inner conductor and the end portion of the dielectric extending through the open channel to reside forward of the first member. The first member resides in a respective one of the at least one receiving channel against the stop surface. The connector assembly also includes second member with an open channel. The second member is slidably coupled to the first end portion of the at least one cable and presses the first member against the stop surface.

    Abstract: An array antenna includes at least one radiating element, which is configured to transmit and receive radio frequency (RF) signals, and a multi RF sub-band combiner circuit electrically coupled to the at least one radiating element. The combiner circuit is configured to: (i) selectively filter and route first and second RF signals in non-adjacent portions of a first sub-band to first and second radio ports, respectively, (ii) pass components of third and fourth RF signals in adjacent portions of a second sub-band to each of the first and second radio ports, and (iii) pass components of fifth and sixth RF signals in adjacent portions of a third sub-band to each of the first and second radio ports. The third sub-band may span higher frequencies relative to the second sub-band, which may span higher frequencies relative to the first sub-band.

    CPC classification number: H01P1/207 ,  H01P5/16

    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.
