The CCI Outdoor Broadband Quadplexer combines 700/800 band (698-862), 900 (880-960), 1800 band (1710-1880), and IMT/IMT-E (1920-2690) bands onto a common port. Specifically intended for use in multi-band systems with limited feeder lines, this CCI Quadplexer facilitates the addition of new technologies including LTE and new spectrum onto 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 the total cost to upgrade a site is significantly reduced. An optional twin unit with two Quadplexers mounted on a single bracket is also available. The CCI Outdoor Quadplexer provides full band performance for each band with low insertion loss, low Intermodulation, and high power handling. Excellent return loss delivers the best match to the antennas and base station, saving precious transmit power. The Quadplexer enables full Remote Electrical Tilt (RET) and Tower Mount Amplifiers (TMA) capability by providing DC and AISG 2.0 compliant pass-through.
Technical Description:
The Outdoor Broadband Quadplexer consists of multiple filters and can be used as either a splitter or combiner to aggregate the 700/800, 900, 1800 and IMT/IMT-E bands on a common feeder line. The fully weatherproof tower mount outdoor Quadplexer provides DC and AISG signal pass-through, enabling power and control for TMA's & RET antennas. The Quadplexer is available with DC/AISG pass options including a smart bias-tee or AISG modem and output port. The Smart Bias-Tee 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. The Quadplexer 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 Quadplexer to minimize any passive intermodulation products from occurring. The Quadplexer housing is constructed from die cast aluminum and consists of an IP67 moisture proof enclosure, with IP68 immersion proof connectors suited to long-life masthead mounting. The Quadplexer 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.
