Designed to combine two 850MHz and a 700MHz base stations, the Kaelus TBC0046 triplexer provides low loss combining with excellent insertion loss and passive inter-modulation performance.


  • Combines legacy CDMA with 10MHz LTE carrier.
  • Extremely close (zero guardband) spacing in 850MHz bands
  • DC/AISG autosensing with LED visual status
  • Offers low insertion loss
  • Low passive IM performance
  • Patent pending

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.
Input voltage range 7.5 – 30V DC

Compliance 3GPP, TS 25.461
