DIPLEXER 698-960/1900-AWS

The Kaelus DBC0037F1V1 cross band coupler combines the lower 698MHz to 960MHz frequency bands with the higher 1900-AWS frequency bands. The diplexer is designed to minimize infrastructure capital expenditure and improve network reliability.


  • LTE ready
  • Auto select DC/AISG pass with built-in lightning protection
  • High band port has DC priority
  • Single or twin configurations available for indoor or outdoor use
  • Monitor port
