Through creative work, the inventor found that in related technologies, in order to support the non-independent networking working mode of the EN-DC architecture and the transmission and reception of 5G NR medium and high frequency signals and ultra-high frequency signals, different radio frequency channels usually need to use multiple relatively An independent power supply module that supports the ET power supply mode is used for power supply. On the one hand, the power supply modules in ET power supply mode are expensive, for example, some cost about 1.5 US dollars, while the cost of power supply modules in APT power supply mode is lower, and the price difference of each module is about 1.3 US dollars; on the other hand, the difference between different RF channels The power supply modules between them are relatively independent, which will cause the RF architecture to occupy more space and is not conducive to the spatial layout of the RF architecture.
