DBC0038F1V1-1

TWIN SAME BAND COMBINER 2100

The Kaelus DBC0038 provides a loss combining solution for combining two Node B, each up to 20MHz bandwidth, onto the same infrastructure thereby saving capital expenditure and costly tower licensing fees.

FEATURES

  • Allows two UMTS2100 Node-Bs to share feeders, TMA’s and antennas.
  • RoHS compliant.
  • For indoor or outdoor use.
  • DC/AISG from Node-B1 ports.
