DBC0157F1V13-2

DIPLEXER 700/850-900

The Kaelus DBC0157 is a bi-directional diplexer designed to combine 700 and 850-900 technologies. The DBC0157 provides low insertion loss and excellent passive intermodulation performance. The DBC0157 can be used at either the BTS or antenna end of the feeder.

FEATURES

  • Enables antenna/feeder sharing for 700 and 850-900 networks
  • Low insertion loss & high return loss
  • Low passive IM performance
  • Multiple DC/AISG bypass configurations available with built-in lightning protection
  • Single and twin models available
