Abstract

The present invention relates to the technical field of radio frequency devices in mobile communications, and more specifically, relates to a phase shifter. The phase shifter comprises a cavity, a feed network provided inside the cavity, and a dielectric element provided inside the cavity and capable of linear movement relative to the cavity. The cavity is formed by connecting at least two sub-cavities in a longitudinal direction, and every two adjacent sub-cavities are mutually insulated. In the present invention, an elongated cavity of a phase shifter is divided into multiple sub-cavities having shorter lengths and formed by connecting the multiple sub-cavities together, thereby reducing processing difficulties of integrally forming a cavity, improving plating quality of the cavity, enabling easy removal of burrs formed in a process of processing the cavity, preventing processing quality issues of the cavity from impacting intermodulation performance metrics of the phase shifter, and improving performance of the phase shifter.

Description

【Technical Field】 [0001] The invention relates to the technical field of mobile communication radio frequency devices, in particular to a phase shifter. 【Background technique】 [0002] In the coverage of mobile communication networks, the electronically adjustable base station antenna is one of the key equipment of the coverage network, and the phase shifter is the core component of the electronically adjustable base station antenna. The performance of the phase shifter directly determines the performance of the electronically adjustable antenna, and then Affect the quality of network coverage, so the importance of phase shifters in the field of mobile base station antennas is self-evident. With the popularization of multi-frequency antennas and the improvement of operators' requirements for antenna performance, the use of multi-port phase shifters for antennas has become a development trend. [0003] In the prior art, the multi-port phase shifter mainly uses a dielectric phase sh...
