Abstract: An apparatus, e.g. a cavity resonator, includes a floor and a cover. A conductive post is located between the floor and the cover and has a void oriented along a longitudinal axis of the post. A dielectric spacer is located between the cover and the post and a dielectric rod is located within the void. A resilient dielectric is located within the void between the dielectric spacer and the floor.

Abstract: Difficulties in grounding a non-integral, deep drawn resonator (DDR) to the filter body of a cavity may be substantially eliminated by preventing the movement of the DDR away from a grounding contact area on the filter body. The addition of a compression plate and stop limiter in the connection of the non-integral DR to the filter body helps insure that any such movement is eliminated or substantially reduced.

Abstract: Corrosion within a flangeless connector, or at an associated connection of a device or medium (e.g., cable), used in a wireless base station may be reduced by incorporating a seating member, e.g., an O-ring, between the connector and a connector port. Conductive plating selectively applied within the connector port may provide a low-resistance ground connection between the port and the connector, while a non-conductive coating selectively applied to a surface against which the seating member is seated may form a weather-tight seal. The connection between the connector and the connector port is thereby protected from moisture, while exposed surfaces of the connector port re protected by the non-conductive coating.

Abstract: Multi-conductor cables for telecommunication systems include a plurality of fiber-optic conductors and/or power conductors extending within an outer jacket in a main body portion of the cable, and extending outside of the outer jacket in a break-out portion of the cable. A break-out boot may be attached to the outer jacket and may surround the conductors in a break-out portion of the cable. Potting material may be provided in the break-out boot within spaces between adjacent conductors to provide innovative sealing of the break-out portion.

Abstract: Sealing portions of an orthomode transducer or another antenna component is accomplished by forming first and second receptacles or channels in one half or portion of the transducer and inserting first and second type of compressible sealing components into the receptacles. Upon attaching additional portions of the transducer the compressible sealing components may be compressed, but the compression is limited to an amount within a compression range to maintain a seal.

Abstract: Orthomode transducers (OMTs) and methods of fabricating OMTs are disclosed. According to disclosed embodiments, an OMT includes a housing defining an internal waveguide. The housing may be composed of a first cast housing member attached to a second cast housing member. The first housing member may include a first side of the waveguide that is cast into the first housing member. The second housing member may include a second side of the waveguide that is cast into the second housing member. A method of fabricating an OMT may include arranging at least one casting insert in at least one mold, casting the housing in the mold and casting a waveguide in the housing using the at least one casting insert. The disclosed devices and methods provide cost effective solutions for fabricating OMTs of various operating frequencies that share a substantially similar outer housing shape and size.
