In the Downlink (DL) path, the Extension Unit provides:
 Automatic Gain Control (AGC) of each converted signal to compensate for
optical losses
 RF amplification of the converted RF signal for transmission while maintaining
an excellent signal-to-noise ratio
 RF filtering to reject spurious emissions
In the Uplink (UL) path, the Extension Unit provides:
 RF amplification to boost the signals received by the antennas to maintain an
excellent signal-to-noise ratio
 RF filtering to reject spurious emissions
 Automatic Level Control (ALC) to adjust the RF signal level to meet blocking
requirements
