Overview

 

CCI’s ATI-77 series of high power low PIM attenuators cover a broad frequency range from 698 to 2700 MHz, while delivering high power performance of up to 100 Watts. Each model has a nominal and highly accurate attenuation value with excellent return loss performance. The units are offered in a wide range of attenuation values from 6 to 20 dB and are ideal for optimizing RF power distribution, which is often required for distributed antenna systems (DAS).

The extremely wide frequency range allows use with multiband and broadband antennas as well as leaky cable systems. The high power handling makes these attenuators well-suited for use with wireless base stations. The attenuators have been designed and constructed with minimal solder joints which assures the correct dissipative loss and enhances the overall reliability.

The attenuators can be wall mounted with the included bracket or rackmount in a single or twin configuration with the optional rack mount kit. 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 9001:2008 certification standards for reliability and quality at our state-of-the-art engineering and manufacturing facilities.
