Overview

 

CCI’s AWS In-Band Low Loss Diplexer with a 15 MHz Guard Band combines two AWS Base Station sub-band outputs onto a single feeder without the insertion loss normally associated with hybrid combiners.  The unit is fully passive and delivers a matched low insertion loss solution for the sharing of common feeder lines and antennas. The unit is provides automatic routing of DC and AISG signals from the individual input ports to the common port.  The unit is housed in a weatherproof outdoor enclosure suitable for tower mount application.

 

Technical Description:

This In-Band Diplexer allows the combining of any two 20 MHz segments in the AWS Tx and Rx Bands separated by a 15 MHz Guard Band.  An efficient, low loss, low PIM, high power quadruplexer combines the band specific Tx/Rx signals at the common port.  The tower mount unit incorporates a unique intelligent Bias-T architecture which passes the DC and AISG carrier frequency from any of the input ports to the common port while blocking the DC and AISG signals from being re-injected into the other input ports.  The tower mount unit is housed in a fully weatherproof IP68 immersion proof enclosure, with IP68 immersion proof connectors suited for long-life masthead mounting.  The unit provides protection against lightning strikes via a multi-stage surge protection circuit.
