The invention discloses a signal amplifier power supply device which is used for supplying power to a signal amplifier. The signal amplifier has a signal output port and a signal receiving port. The signal amplifier power supply device comprises a power line interface which is connected to the power supply, a voltage conversion circuit which converts the output voltage of the power supply into the rated voltage needed by the signal amplifier, and a slot interface which receives the signal amplifier. By using the signal amplifier power supply device of the invention, a machine platform motherboard can be directly placed to supply power to the signal amplifier, since the operation times of machine platform start-up and shutdown is avoided, the working efficiency is effectively improved. In addition, since the detection personnel do not need to touch the machine platform motherboard, the scrap of the motherboard is avoided, and the cost of production is effectively saved.
Description
[0001] 【Technical field】 [0002] The invention relates to a power supply device, in particular to a signal amplifier power supply device. [0003] 【Background technique】 [0004] At present, the signal amplifier has been widely used in Bluetooth, wireless network card and other devices. Usually, the signal amplifier needs to be connected to a machine main board, and the voltage is converted into a rated voltage in line with the signal amplifier through the machine main board (the signal amplifier is directly connected to the power supply, which is easy to burn out. ). When the signal amplifier is tested for performance before leaving the factory, one end of the signal amplifier is generally connected to the main board of a machine, and the other end is connected to a measuring instrument, and then the machine is started to provide power and a test signal to the signal amplifier through the main board. , the signal amplifier transmits the amplified test signal to the measuring...
