Abstract

The invention relates to the technical field of a mobile communication radio frequency device, and specifically relates to a phase shifter. The phase shifter comprises a cavity, a feed network arranged in the cavity, and a dielectric element which is arranged in the cavity and can perform linear motion relative to the cavity, wherein the cavity is formed by at least two sub cavities spliced in a lengthwise direction; and the adjacent two sub cavities are insulated. By dividing the long cavity of the phase shifter into a plurality of sub cavities with relatively short lengths, and by splicing the multiple sub cavities into the cavity of the phase shifter, the processing difficulty in integral forming of the cavity is lowered, the electroplating quality of the cavity is improved, burrs generated in cavity processing can be removed conveniently, and influence of the processing quality problem of the cavity to the intermodulation index of the phase shifter can be avoided, thereby improvingthe 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 network, the electric adjustable base station antenna is one of the key equipment of the coverage network, and the phase shifter is the core component of the electric adjustable base station antenna. The performance of the phase shifter directly determines the performance of the electric adjustable antenna, and then It affects the coverage quality of the network, so the importance of phase shifters in the field of mobile base station antennas is self-evident. With the popularity of multi-frequency antennas and the improvement of operators' requirements for antenna performance, it has become a development trend to use multi-port phase shifters for antennas. [0003] In the prior art, the multi-port phase shifter mainly adopts a dielectric phase shifter, ...
