CCI’s QCO-55 series of outdoor directional couplers cover a broad frequency range from 370 to 3600 MHz, while delivering high power performance of up to 750 Watts at the input port. Each model has a nominal coupling value with very low insertion loss and excellent return loss performance. The units are offered in a wide range of coupling values and are ideal for optimizing RF power distribution, which is often required for distributed antenna systems (DAS).

The extremely wide frequency range of the couplers enables their use with multiband and broadband antennas as well as a both active and passive DAS systems. The CCI couplers are also rated for outdoor use; this along with the high power handling makes them well-suited for use with wireless base stations. The design of CCI's directional couplers provides for extremely low insertion loss and excellent PIM performance. These units are constructed with a weatherproof aluminum IP67 rated housing and with IP67 immersion rated connectors which enhances the overall reliability.

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.
