The DBC0058 combiner provides diplexing of LTE800 and EGSM900 signals whenever both signals are required on a single output. With DC throughput configured in the factory, the combiner can be used at either the BTS end or at the antenna.


  • Used to combine 800 and 900MHz systems minimizing hardware installation cost
  • Low insertion loss with 50dB port to port isolation
  • Options for bypassing DC and AISG internal to the diplexer
  • Suitable for outdoor and indoor applications, Wall or mast mounting
