Patent number: 9979101Abstract: 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.Type: GrantFiled: April 26, 2017Date of Patent: May 22, 2018Assignee: Nokia Shanghai BellInventors: Yin-Shing Chong, Timothy Bernhardt

Patent number: 9843087Abstract: 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.Type: GrantFiled: May 2, 2017Date of Patent: December 12, 2017Assignee: Alcatel-Lucent Shanghai Bell Co Ltd.Inventors: Yin-Shing Chong, Peter Casey, Yunchi Zhang

Patent number: 9742050Abstract: 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.Type: GrantFiled: January 17, 2014Date of Patent: August 22, 2017Assignee: Alcatel-Lucent Shanghai Bell Co., Ltd.Inventors: Yin-Shing Chong, Yunchi Zhang, Peter A.

Patent number: 9680194Abstract: 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.

Publication number: 20160268726Abstract: 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 recessed portion in an outer surface of a body of the flangeless connector. The recessed portion helps retain a seating member, such as a deformable O-ring, to prevent water and other environmental material from seeping into the connector or connection. Further, inner surfaces of a port of a device that receives the flangeless connector may be covered with a conductive plating, while outer surfaces of the port may be covered with a non-conductive coating.Type: ApplicationFiled: March 12, 2015Publication date: September 15, 2016Applicant: Radio Frequency Systems, Inc.Inventors: Yin-shing Chong, Timothy Bernhardt
