  DUP181921 Topview  
  • Two Double Duplexers in a single 1U Height “Rack Mountable” Tray
  • Unduplexes fully duplexed cabinets for RXAIT
  • Ideal for adding additional cabinets of the same type
  • Combines Tx and Rx BTS outputs onto a common feeder
  • Two Duplexers in one housing
  • Integrated Bandpass
  • Optional second (or “Expansion”) Duplexer can be installed adjacent to the  first Duplexer on the Tray
  • DC Pass-Through now available on “New” 1900 MHz Duplexers.  DC ports are mounted on the Duplexer Front Panel

 

Overview

 

 

 

CCI’s Double Duplexer combines Tx and Rx paths onto a common feeder.  The Tx filter provides a low insertion loss, high power handling path, with high rejection of the receive band.  The Rx filter passes the full receive band and provides significant rejection to a broad spectrum, with a minimum of 90 dB in the Tx Passband.  The Tx filter is a high Q design optimized for low insertion loss with high power handling.  The duplexer is designed to be expandable.  A second unit can be installed adjacent to the first unit, saving rack space for a total of four (4) duplexers in a 1U high space.  The above photo shows the standard unit “without” the optional second unit.  DC ports allow for Bias of TMA’s.  Note: “Old” Duplexer units do not have DC-Pass-Through.
