Abstract

The application discloses a 5G communication device, a combiner/divider and a current detection circuit thereof, the current detection circuit comprises a current sampling resistor, an adjusting module and a detection module, one end of the current sampling resistor is connected with the input end of the current detection circuit and the first input end of the adjusting module; the other end of the current sampling resistor is connected with the output end of the current detection circuit and the second input end of the adjusting module, the adjusting module is coupled with the detection module, and the detection module detects the detection voltage through the adjusting module and calculates the current of the current sampling resistor according to the detection voltage. According to the invention, low-cost current detection can be realized, and meanwhile, the voltage detection range is enlarged.

Description

technical field [0001] This application relates to the field of communication, especially a 5G communication device, a combiner and a splitter, and a current detection circuit thereof. Background technique [0002] In the 5G (5th-Generation, fifth-generation mobile communication technology) combiner and splitter, a DC bypass needs to be added to the combiner and splitter. The power supply of the base station can provide DC voltage through the DC bias device and this DC bypass function. To the next level equipment, such as tower amplifier, antenna control unit and so on. In the actual application process, the output port may be short-circuited, or the current consumption may be abnormal due to the failure of the subsequent equipment. Therefore, the current detection circuit needs to be applied to the output port of the combination and branch to detect the current consumption of the subsequent equipment. The low-noise amplifier generally judges whether the low-noise amplifier...
