What is the function of rfu in huwaei bts?

In Huawei BTS (Base Transceiver Station) systems, RFU (Radio Frequency Unit) plays a crucial role in processing radio signals. It converts the digital signals from the baseband unit into radio frequency signals for transmission and vice versa for reception. Additionally, the RFU manages power amplification, signal filtering, and frequency conversion, ensuring efficient communication and optimal performance of the cellular network.
