CCI’s Low Loss PCS In-Band Combiner combines two Base Station outputs on the A and D plus E thru G sub-bands of the PCS (1900 MHz) band 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 requires no power and has a DC Block on the Input ports. Optional AISG port which connects to an AISG Modem that provides DC + AISG signal to power TMA’s and Antennas is available. The unit is housed in a weatherproof outdoor enclosure suitable for tower mount application.

Internal duplexers deliver signal to independent Tx and Rx filter combiners, enabling a high level of control and performance to maintain good isolation while minimizing insertion loss. Stages are kept to a minimum to maximize power and efficiency. Transmit paths are fully isolated from Receive paths to prevent intermodulation products. The tower mount unit consists of multiple band-pass filters and an optional AISG Modem which are all housed in an IP67 moisture proof enclosure, with IP68 immersion proof connectors suited for long-life masthead mounting. The unit provides protection against lightning strikes via a multi-stage surge protection circuit.
