      Broadband Outdoor Diplexer DPO-3946-xxx
                
       
       
         
  DPO3946MT2 FV  
  • Combines two frequency ranges 380-960 MHz with 1425-2690 MHz onto a single common port.
  • The low band port covers the 600, 700, 850 and 900 bands covering 380-960MHz and the high band port covers 1400, 1800, 2100, AWS, PCS, WCS and BRS bands.
  • High power 200 W per port with low insertion loss in a small, lightweight enclosure
  • Low intermodulation with isolation of >50 dB port to port
  • Available dual unit configuration
  • High reliability of >500K Hours MTBF and multi-strike lightning protection
  • Available outdoor pole or wall mounting options

 

Overview

 

The CCI Outdoor Broadband Diplexer passes 600, 700, 850 and 900 bands covering 380-960 MHz on its low band input port and 1400, 1800, 2100, AWS, PCS, WCS and BRS bands covering 1425-2690 MHz on its high band input port. The Diplexer combines the low band and high band signals on to a common port and is specifically intended for use in multi-band systems with limited feeder lines. The Diplexer facilitates the addition of new technologies including LTE and new spectrum to existing sites while providing a high degree of isolation between systems. Decreasing the number of feeder lines lowers tower loading, leasing and installation expenditures and significantly reduces the total cost to upgrade a site.
The Diplexer provides full band coverage for each band with low insertion loss, low Intermodulation, and high 200 W per port power handling. Excellent return loss performance delivers the best match to the antennas and base station, saving precious transmit power. The CCI Diplexer enables Remote Electrical Tilt (RET) and Tower Mount Amplifiers (TMA) control capability by providing DC/AISG 2.0 compliant pass-through on either input or via optional AISG output. It is available in single or twin unit configuration.

 

Technical Description:

The CCI Outdoor Broadband Diplexer consists of multiple filters and can be used as either a splitter or combiner to aggregate the 600/700/850/900 with the 1400/1800/2100/AWS/PCS/WCS/BRS bands on to a common feeder line. The fully weatherproof tower mount outdoor Diplexer provides DC and AISG signal pass-through on either of the band specific ports, enabling power and control for TMA's & RET antennas. The Smart Bias-T architecture passes the DC and AISG carrier frequency from any one of the input ports to the common port while blocking the DC and AISG signals from being re-injected into the other input ports. An optional AISG Modem allows AISG signal and DC to be output via an AISG output port. The Diplexer has internal multi-strike lightning protection using a multi-stage surge protection circuit.
The unit has been designed to minimize insertion loss while maximizing isolation. Particular attention has been given to the intermodulation performance of the Diplexer to minimize any passive intermodulation products from occurring. The Diplexer housing is constructed from die cast aluminum and consists of an IP67 moisture proof enclosure, with IP67 moisture proof connectors suited to long-life masthead mounting. The Diplexer can be pole or wall mounted with the included bracket. The RF ports can be configured with either DIN 7-16 or 4.3-10 connectors.
CCI filter and combiner products are designed and produced to ISO 9001 certification standards for reliability and quality at our state-of-the-art engineering and manufacturing facilities.
