Overview

 

 

 

CCI’s Dual Duplexer combines Tx and Rx paths onto a common feeder.  Provides Duplexing of UMTS and GSM onto a single feeder without the loss normally associated with passive combiners.  Separate isolated receive paths permit connection of multiple components, such as CCI’s RX-AIT (Multicoupler).  The Tx filter is a high Q design optimized for low insertion loss with high power handling.  The Rx1 filter provides significant rejection in the Tx band, while maintaining low loss.  The Rx2 filter provides moderate rejection in the Tx band.
