CCI’s QC-0727 series of directional couplers covers a broad frequency range from 698 to 2700 MHz, while delivering high power performance at 500 W for units with DIN and 4.3-10 connectors and 300 W for units with N-type connectors. 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 use with multiband and broadband antennas as well as well as wide variety of DAS systems including leaky cable. The CCI couplers with the 7-16 DIN and 4.3-10 connectors are also rated for outdoor use; this along with the high power handling makes them well-suited for use with wireless base stations. The air dielectric design of CCI's directional couplers provides for extremely low insertion loss and excellent PIM performance. These units have been constructed with minimal solder joints which enhances the overall reliability.
