pRRU5921

The pRRU5921 processes RF signals. It provides the following functions:

  • Modulates baseband 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, and sends them to the BBU for processing.
  • Transmits CPRI data over Ethernet cables or optical fibers.
  • Uses internal antennas.
  • Supports PoE and DC power supply.
  • Supports flexible configuration for multi-mode multi-band operation.
