pRRU5918

The pRRU5918 processes RF signals. It provides the following functions:

  • Modulates digital signals to a transmit frequency band, filters and amplifies these signals, and sends them to the antenna for transmission.
  • Receives RF signals from antennas, filters and amplifies these signals, down-converts the signals, converts them to digital signals, and sends them to the BBU/DCU for processing.
  • Transmits CPRI data over Ethernet cables.
  • Supports external antennas.
  • Supports PoE power supply.
  • Supports flexible configuration for multi-mode, multi-band operation.
