DBC0099F5V51-1

TWIN SAME BAND COMBINER 1900

Designed to combine two 1900MHz base stations, the Kaelus DBC0099 provides a low loss combiner with excellent insertion loss and passive inter-modulation performance.

FEATURES

  • Combines two 1900MHz BTS onto a single feeder without guard band
  • Designed for low passive inter-modulation
  • DC/AISG bypass field selectable
  • Very low insertion loss
