Patent number: 11056782Abstract: A linked locking mechanism and antenna down-tilt angle control device is described. Linked locking mechanism includes: mounting frame with a mounting positions, each mounting position has a mounting through hole and a clamping body. Output assembly includes an output shaft and output gear resiliently disposed on output shaft. One end of output gear has engaging body engaged with clamping body and pressing body provided through mounting through hole. Rotating bracket has pressure bearing surface pressed against pressing body. Arc-shaped embossments are provided on pressure bearing surface. The arc-shaped embossment includes guide end, anti-reverse end, and mating body. When mating body and pressing body abut, and engaging body and clamping body are separated, output gear drives output shaft to rotate. Linked locking mechanism and antenna down-tilt angle control device provide easy positioning and accurate control of down-tilt angle of antenna.Type: GrantFiled: August 29, 2018Date of Patent: July 6, 2021Inventors: Chaosheng Huang, Zefeng Ma, Fengzhang Xue, Jianjun You, Hongbin Duan, Peitao Liu

Patent number: 10062940Abstract: A dielectric phase shifter comprises a cavity having an elongated receiving space, a phase shifting circuit disposed inside the receiving space, and a dielectric element slidably mounted in the receiving space and parallel with the phase shifting circuit. A rail is disposed on an inner wall of the cavity for preventing contact between the movable dielectric element and the phase shifting circuit. By providing a number of rails between the phase shifting circuit and the dielectric element, direct contact between the dielectric element and a feeding network is prevented. As a result, no additional force will be imposed on the feeding network and reliability is enhanced. Moreover, wear of the feeding network and/or dielectric element during operation of the phase shifter is eliminated.Type: GrantFiled: January 27, 2015Date of Patent: August 28, 2018Inventors: Peitao Liu, Guosheng Su, Binlong Bu, Fengzhang Xue, Shanqiu Sun

Patent number: 10062939Abstract: A phase shifter of cavity type includes an integrally formed cavity, a feeding network disposed inside the cavity, a dielectric element disposed between the feeding network and the cavity, and at least one transmission-line transformation device. The at least one transmission-line transformation device is connected with the cavity by welding for connecting an outer conductor of a transmission cable, and for passing an inner conductor of the transmission cable into the cavity and being connected with the feeding network. Phase shifting is achieved by straight movement of the dielectric element along the longitudinal direction of the cavity. For the phase shifter of cavity type, the cavity and transmission-line transformation device are individually designed, and as a result, difficulty in design and manufacture is decreased. In addition, fasteners such as screws are not used for securing the phase shifter, thus avoiding reliability and inter-modulation problems resulted from failure of screws.Type: GrantFiled: January 27, 2015Date of Patent: August 28, 2018Inventors: Peitao Liu, Guosheng Su, Litao Chen, Binlong Bu, Fengzhang Xue, Shanqiu Sun

Patent number: 9780425Abstract: A microwave component of cavity type includes an integral cavity and a microwave network circuit disposed in the cavity. The cavity has multiple enclosing walls and a chamber defined by said multiple enclosing walls. The chamber is intended for accommodating the microwave network circuit therein. A wiring slot is defined in at least one of the enclosing walls, and at least one first through hole extended through the chamber is provided on each wiring slot. The microwave component of cavity type features small size, simple structure, and wide application. Furthermore, cost may be reduced, batch production may be achieved, use of fasteners such as screws is avoided, and the passive inter-modulation products caused by fasteners are eliminated, as the microwave component is secured without any screws.Type: GrantFiled: January 27, 2015Date of Patent: October 3, 2017Assignees: COMBA TELECOM SYSTEMS (CHINA) LTD., COMBA TELECOM TECHNOLOGY (GUANGZHOU) LTD., COMBA TELECOM SYSTEMS (GUANGZHOU) LTD., TIANJIN COMBA TELECOM SYSTEMS LTD.Inventors: Peitao Liu, Guosheng Su, Fengzhang Xue, Litao Chen, Binlong Bu
