  • Combines 850 and 1900 basestations onto a single feeder
  • Two diplexers in a single 1U high tray
  • DC inputs for passing bias through 1900 path
  • Very low insertion loss

Overview

 

Communication Components, Inc. Dual Diplexer combines 850 and 1900 band basestations onto a single feeder.  The unit is a single 19” 1U tray, containing two diplexers.
The CCI Dual Diplexer provides full band performance in each band with low insertion loss,  low IMD’s, and  high power handling.  Excellent return loss delivers the best match to the antennas and basestation, saving precious transmitter power.
Each input port is highly isolated from the other ports.  The unit employs D.C. pass-through in the 1900 path to provide power to Tower Mount Amplifiers (TMA’s / TTA’s).
