Problems solved by technology

The assembly time of 4 groups or 8 groups of combiners is longer, and because each group of single combiners has a metal frame around it, the circuit boards used for the design margin of the single combiner will be larger, and the entire combiner cost will be higher

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as Figure 1 to Figure 9 As shown, the present invention provides an integrated circuit combiner, which includes a circuit board 1 and a metal frame 2 folded around. There are 8 combiner units 4 on the circuit board 1, and the 8 combiner units 4 Arranged side by side, each combiner unit 4 has an output port 11 and an input port, each combiner unit 4 is composed of two filters, and the filters are combined and output through the output port.

[0030] Such as Figure 1 to Figure 7 As shown, the integrated combiner of the present invention mainly includes a radio frequency path circuit board 1 for working in at least two different frequency bands without interfering with each other, a metal frame 2 folded around, and the circuit board 1 is placed close to each other. Inside the metal frame 2, there is a metal cover plate 3 above the metal frame 2.

Abstract

The invention discloses an integrated combiner which comprises a circuit board and a metal frame, wherein the periphery of the metal frame is folded. The circuit board is provided with a plurality of combiner units which are integrally distributed side by side, each combiner unit is provided with an input port and an output port, and each combiner unit enables at least two filters to be output through the corresponding output port after the filters are combined. According to the integrated combiner, the multiple combiner units are designed in an integrated mode, miniaturization of the combiner is achieved, the size of an antenna is smaller, and the weight of the antenna is lower; due to the fact that the two filters are arranged in each combiner unit, the output end of each filter is provided with a microstrip line with the length 1 / 4 lambda the center frequency of a corresponding frequency band, influences between frequency bands are eliminated, the anti-interference capacity is strong, the design margin of each combiner unit is little, the whole combiner can be miniaturized, more space margin can be supplied to design of other components in the antenna of a base station, cost of the antenna is reduced, and large-scale assembling and debugging are facilitated.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an integrated combiner. Background technique [0002] In a cellular mobile communication system, the base station antenna is a key subsystem component, and the performance of the base station antenna directly determines the signal coverage and key indicator performance of the entire cellular mobile communication system. [0003] With the development of the first generation, second generation, third generation and even the latest fourth generation LTE mobile communication system, base station antenna technology has also been rapidly developed and updated. In modern mobile communications, many different systems, different frequency bands, and even different operators share a site, which objectively promotes the development trend that the same base station antenna needs to support multiple different frequency bands and different systems at the same time, which is also in line wit...
