DIPLEXER 600-700/850

The Kaelus DBC0108 is a bi-directional Diplexer designed to combine 600 & 700 with 850 technologies, the DBC0108 provides excellent insertion loss and passive intermodulation performance. Bidirectional passage of DC/AISG is provided in this outdoor product.

FEATURES

  • Enables antenna/feeder sharing for 600-700 and 850 networks
  • Designed and 100% tested for low passive intermodulation
  • Autosense of DC allows operation at the bottom or the top of the tower
  • Very low insertion losses
  • Good Return Loss

dc / aisg
The DC/AISG path is automatically selected. In bottom of the tower applications (combiner mode), each RF channel port is sequentially checked for the presence of DC voltage. If more than one port has voltage, the port that has the highest (programmed) priority is passed to the common port. If a short circuit is detected on the common port DC/AISG is disabled. In top-of-tower applications (splitter mode), DC/AISG is passed to all ports that do not present a short circuit. If a short circuit is detected, the shorted RF port will be disabled for DC/AISG while other RF ports remain connected.
