Description

Technical Field

[0001] The utility model relates to the technical field of wireless communications, in particular to a C-band power division network. Background Art

[0002] Power splitting networks can split one input signal into two or more output signals, enabling flexible signal distribution in complex communication networks. The C-band, a radio frequency band between 4 and 8 GHz, has broad application prospects in wireless communications, particularly in the construction of 5G networks. Therefore, how to distribute C-band signal power to meet the signal transmission needs of multiple devices is extremely important.

[0003] The currently disclosed patent is named "C-band signal conversion equipment" and is a Chinese utility model patent with the publication number CN220234665U. This patent includes a front-end preprocessing module, a frequency conversion module, a first intermediate frequency processing module, and a second intermediate frequency processing module. The detection module of this patent can control the digital control attenuation module to process the signal according to the detection results to ensure stable signal output. However, the processing method of the digital control attenuation module is generally to compensate the signal by adjusting the resistance value. In the case of a power division network failure and a large error signal, the digital control attenuation module will also compensate, which may mask the actual fault condition of the power division network, resulting in the staff being unable to discover and handle the fault in time. If the fault condition in the power division network is not handled for a long time, it is easy to cause the power division network to collapse. Utility Model Content

After the amplification is completed, the amplification circuit sends the signal to the analog-to-digital conversion circuit connected thereto. After the analog-to-digital conversion circuit converts the signal, the analog-to-digital conversion circuit transmits the resulting signal to the processor.

The parameters of the compensation module are adjusted in real time according to the signal at the output end of the power division module, so that the signal after power division is more accurate. If the signal error at the output end of the power division module is large, the processor will promptly send an alarm message to the staff to avoid the fault situation in the power division network not being handled for a long time and causing the power division network to crash.
