A dual-frequency tower top amplifier for improving the reception sensitivity of a base station

Abstract

The invention relates to a dual-frequency tower top amplifier for improving the receiving sensitivity of a base station, which comprises a heat sink, an upper case, a right chassis, a lower case, a left chassis, an output end, a grounding bolt, an input end, a through hole, a clasp groove and a hinge. The lower end of the upper shell is provided with a lower shell, and the lower shell is connectedwith the upper shell through a hinge; the top side of the upper shell is provided with a heat radiating fin, and the heat radiating fin and the upper shell are of an integrated structure; a left endsurface of that low shell is provided with an output end, and the output end is connected with the lower shell in an embedded manner; the right side of the output terminal is provided with a groundingbolt, and the grounding bolt is connected with the lower shell through an embedded mode. The invention has the advantages of wide coverage, firm installation, high efficiency and strong reliability through the improvement of a dual-frequency tower top amplifier for improving the receiving sensitivity of a base station, thereby effectively solving the problems and shortcomings proposed in one itemof the background technology of the invention.

Description

technical field [0001] The invention relates to the technical field of amplifiers, more specifically, to a dual-frequency tower-mounted amplifier that improves the receiving sensitivity of a base station. Background technique [0002] The tower mount amplifier is a low-noise amplifier installed on the top of the tower close to the receiving antenna. It can amplify the received signal by nearly 12dB before the received signal enters the feeder, improve the quality of the uplink signal, improve call reliability and voice quality, and at the same time Expand the coverage area of ​​the community. [0003] For GSM network coverage, there is a prominent contradiction in the relationship between coverage and capacity in rural areas; the main manifestation is that there is excess capacity but insufficient coverage. Therefore, a large number of rural areas use single carrier frequency. Due to the vastness of rural areas, often use The way of crossing towers will increase the constru...

Problems solved by technology

[0003] For GSM network coverage, there is a prominent contradiction in the relationship between coverage and capacity in rural areas; the main manifestation is that there is excess capacity but insufficient coverage. Therefore, a large number of rural areas use single carrier frequency. Due to the vastness of rural areas, often use The way of crossing the tower increases the construction cost; in addition, after the antenna tower is crossed, the RF transmission line will be lengthened and the loss will increase, the output power of the antenna will further decrease, and the coverage will further decrease
