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: 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
