Description
Technical Field
The application relates to a signal amplifier, in particular to a built-in antenna mobile phone signal amplifier.
Background
Note that the contents described in this section do not represent all the related art.
When no mobile phone signal exists in a household, a mobile phone signal amplifier needs to be additionally installed, when the mobile phone signal amplifier is installed, a retransmission antenna and a cable need to be installed, when the antenna is installed, a hole needs to be drilled on a wall, and the like, so that the layout and the attractiveness of the interior of the household are affected.
At present, a plurality of mobile phone signal amplifiers are manufactured, a few mobile phone signal amplifiers adopt a built-in antenna mode, the traditional realization mode is that a retransmission antenna adopts an independent transmitting antenna, and the retransmission antenna and equipment are integrated into a whole, so that the self-excitation problem of the mobile phone signal amplifier is particularly solved, if the equipment is self-excited, the equipment cannot work, and the work of a base station is influenced, so that the normal communication of other mobile phones in the coverage range of the base station is influenced.
The self-excitation phenomenon is caused because the amplifier is a weak current system and has high sensitivity, so that the amplifier can easily receive random voltage output from the outside and the inside, in addition, the self-excitation phenomenon can also be caused because the installation position of the retransmission antenna is unreasonable, and the self-excitation of the equipment is eliminated by adjusting the isolation between the donor antenna and the retransmission antenna in the traditional mode. The device can be installed by non-professional people, and the device is difficult to install by the non-professional people and cannot achieve the expected effect.
