DBC0097F2V51-1

TWIN SAME BAND COMBINER, 1900

Designed to combine two 1900MHz BTS with minimum 5MHz spacing, the Kaelus DBC0097 provides a compact twin combining solution with low insertion. The DBC0097 solution minimizes feeders, TMA's and antennas thereby saving both capital and operational expenditure when combining two base stations.

FEATURES

  • Allows CDMA and LTE base stations to share feeders, TMAs and antennae
  • Low downlink and uplink insertion losses
  • DC/AISG bypass field settable
  • Suitable for indoor and outdoor use
  • Down to 5MHz guard band
