Abstract: A metallized dielectric waveguide filter includes first and second input/output ports and a dielectric block that has metallized top and bottom surfaces and metallized sidewalls. The dielectric block further includes a plurality of metallized openings that extend into the interior of the dielectric block, and these metallized openings divide the dielectric block into a plurality of resonator cavities. A first of the metallized openings extends at an oblique angle with respect to a first of the metallized outer sidewalls.

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.

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: A resonant cavity filter has a housing having a resonator mounted therein, a tuning screw that comprises a head portion, a metallic tuning element and a dielectric spacer interposed between the head portion and the metallic tuning element. The tuning screw is mounted for coaxial insertion into an interior of the resonator to adjust a frequency response of the resonant cavity filter.

Abstract: A bracket for mounting a device to support structure has (i) a first side and (ii) second and third sides that extend perpendicularly from opposite edges of the first side in the same direction, such that the second and third sides are parallel to each other. The bracket supports a first mounting configuration in which the first side is attached to a face of the device and the second side is attached to a plane of the support structure such that the side of the device is perpendicular to the plane of the support structure. The bracket also supports a second mounting configuration in which the third side is attached to the face of the device and the second side is attached to the plane of the support structure such that the face of the device is parallel to the plane of the support structure.

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.
