Description

technical field

[0001] The invention relates to the technical field of power splitters, in particular to a noise reduction device for active power splitters. Background technique

[0002] Active power amplifiers are widely used by residents because they can provide different output voltages, and one input port can be connected to multiple output ports, which can transfer one signal to multiple signals. However, the internal working parts of active power amplifiers will The generation of a certain amount of noise will affect the use of consumers, which has led to the uncommon use of active power amplifiers in the home for a long time. Contents of the invention

[0003] The object of the present invention is to provide a noise reduction device for an active power divider. The casing has good sealing performance, and the noise reduction device is improved inside the casing to reduce noise and improve the use environment, so as to solve the problems mentioned in the background...
