Broadband DIN inductive radio frequency arrester

Abstract

The invention discloses a broadband DIN inductive radio frequency arrester which comprises a body, a back end main body, an internal conductor A, an internal conductor B, an insulator and a spike. The body is hollowed, the center line of the back end main body is perpendicular to that of the body hollow, the back end main body is movably connected with the body, the back end main body is hollowed, and the hollow of the body is communicated with the hollow of the back end main body; the internal conductor A is arranged in the hollow of the body, and is insulated from the inner wall of the body through the insulator; the internal conductor B is arranged in the hollow of the back end main body; the internal conductor A is perpendicular to the internal conductor B, and one end of the internal conductor B is fixed with the internal conductor A; the middle part of the internal conductor B is spring-shaped, the spike is arranged between the other end of the internal conductor B and the end surface of the back end main body, the center of the spike shares an identical axle with the center of the back end hollow, and the internal conductor B can be compressed through adjusting the position between the back end main body and the body; and the broadband DIN inductive radio frequency arrester can be widely applied to base station, microwave communication system and mobile communication field.

Description

technical field [0001] The invention relates to a lightning arrester, in particular to a wide-band DIN inductive radio frequency lightning arrester, which belongs to the technical field of new radio frequency microwave devices. Background technique [0002] The types of arresters are basically divided into three types: one is the power arrester, according to the voltage, it is divided into 220V single-phase power arrester and 380V three-phase power arrester; Antenna feeder arrester, which is suitable for communication transmitter antenna system and radio signal receiving equipment system. This specialized product belongs to the antenna feeder arrester. [0003] At present, the domestic and foreign products of antenna feeder arrester include "gas discharge tube arrester" and "λ / 4 arrester". In foreign countries, this type of arrester has a relatively high technical level, a long history of research and development, and rapid development. Low (≤1.20); low intermodulation (≤-...

AI Technical Summary

Problems solved by technology

Domestic manufacturers are developing towards the international advanced level. On the one hand, domestic manufacturers of similar products are trying to digest and absorb international advanced technology, and at the same time trying to innovate in product technology; on the other hand, they are trying to compete with foreign manufacturers for market share, and their development speed is also increasing Very fast; but its standing wave ratio coefficient is high (≤1.25), intermodulation index is high (≤-150dBc), the working frequency is continuous frequency, the frequency band is narrow 0.8GHz~2.2GHz, and the external dimension is large
