    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.

    Abstract: A metallized dielectric waveguide filter includes an upper metallized dielectric waveguide having a plurality of upper resonant cavities, the upper metallized dielectric waveguide comprising an upper dielectric block having metallized outer walls, and a lower metallized dielectric waveguide having a plurality of lower resonant cavities, the lower metallized dielectric waveguide comprising a lower dielectric block having metallized outer walls. A first of the upper resonant cavities is operatively connected to a first of the lower resonant cavities via at least one coupling window. A first slot having metallized walls is provided in a portion of the upper dielectric block that is part of the first of the upper resonant cavities.

    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.
