FlexWave PRUs control RF emissions, interface with the FlexWave Prism Host Unit II and perform the optical to
electrical conversion for transport to the antennas. The PRU is an environmentally-sealed unit designed for
outdoor use that houses the electronic assemblies such as the Digital/Analog Radio Transceiver (DART) board
and the Power Amplifier, and seals out dirt and moisture. The PRU uses fans located on the top of each unit to
cool its chassis. The antenna cable connectors, fiber connectors, AC or DC power connector, and the unit status
indicator are located on the bottom of the unit.
A PRU supports or provides the following basic functions:
•
Receives on the forward path the digitized spectrum from the Host and converts the spectrum back into an
RF signal to be distributed via an externally mounted antenna system. On the reverse path, the PRU digitizes
the designated RF spectrum and digitally transports it over single mode fiber or Millimeter Wave (MMW) to
the Host.
•
Provides RF interface (antenna port) for the antennas.
•
Accepts either AC or DC power input.
