CCI’s AWS same band low loss diplexer with a "0" MHz guard band combines two base station sub-band outputs, any combination CDMA, UMTS and/or LTE, onto a single feeder without the insertion loss normally associated with hybrid combiners. The unit is fully passive and delivers a matched low insertion loss solution for the sharing of common feeder lines and antennas. The unit is completely passive and provides automatic routing of DC and AISG signals from the individual input ports to the common port. The unit is housed in a weatherproof outdoor enclosure suitable for tower mount application.

This low loss diplexer allows the TX/RX combining of any 5, 10 or 15 MHz segment in the AWS TX and RX Bands separated by a "0" MHz Guard Band. Complementary Bandpass/Bandstop filters maintain good isolation while minimizing insertion loss. Transmit paths are fully isolated from Receive paths to prevent intermodulation products. The fully weatherproof tower mount unit incorporates a unique intelligent Bias-T architecture which passes the DC and AISG carrier frequency from any 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 tower mount unit consists of multiple band-pass filters which are all housed in a fully weatherproof IP67 immersion proof enclosure, with IP67 rated connectors suited for long-life masthead mounting. The same band diplexer is available in a twin or single configuration and provides protection against lightning strikes via a multi-stage surge protection circuit. 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.
