Description

Technical Field

[0001] The utility model relates to the technical field of broadband amplifiers, in particular to a dustproof structure for broadband amplifiers. Background Art

[0002] As we all know, a broadband amplifier is a device used to increase the strength and bandwidth of telecommunication signals, and is usually used in wireless communications, wired communications, and various electronic devices. A broadband amplifier can amplify signals within multiple frequency ranges, so it is called "broadband", and is not limited to signals of a single frequency. In order to facilitate heat dissipation, a broadband amplifier will be provided with heat dissipation holes, and dustproof nets are generally provided on the heat dissipation holes to prevent external dust from entering the broadband amplifier.

[0003] However, the dustproof structure of the existing broadband amplifier is generally fixed on the heat dissipation holes of the broadband amplifier. When the dustproof structure is used for a long time and some dust and lint on the dustproof structure need to be cleaned, since the dustproof structure is fixed on the heat dissipation holes, it is not convenient to clean one side of the dustproof structure inside the body, which will lead to incomplete cleaning and cause dust and lint to adhere to the dustproof structure, thereby affecting the heat dissipation efficiency. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a dustproof structure for a broadband amplifier.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a dust-proof structure for a broadband amplifier, which has the following beneficial effects:

[0015] The dustproof structure for the broadband amplifier has a detachable dust net, so that when the dustproof net needs to be cleaned, the dustproof net can be removed for cleaning, thereby avoiding the situation in which, as in the traditional structure, the dustproof net is fixed on the heat dissipation hole, making it inconvenient to clean the dustproof net on one side of the main body, resulting in some dust and fluff attached to the dustproof net, thereby avoiding the influence of dust and fluff on the heat dissipation effect.
