The CCI Outdoor Broadband Diplexer passes VHF bands covering DC-490 MHz on its low band input port and 694-960/1700-2700/3300-3800 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 300 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 the low band port to the common port. It is available in single or twin unit configuration.

The CCI Outdoor Broadband Diplexer consists of multiple filters and can be used as either a splitter or combiner to aggregate the VHF (DC-490 MHz) with the 694-960/1700-2700/3300-3800 MHz bands on to a common feeder line. The fully weatherproof tower mount outdoor Diplexer provides DC and AISG signal pass-through, enabling power and control for TMA's & RET antennas. The Bias-T passes the DC and AISG carrier frequency from the low bad input port to the common 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 areconfigured with 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.
