Overview
|
CCI’s Twin Low Loss fully integrated Filter-Combiner combines two operators or two technologies (eg GSM and LTE) on sub-bands of the 2100 band onto a single feeder without the insertion loss normally associated with passive 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 a totally passive low loss filter and no power is required. DC pass is provided as an option if required. The input ports will sense the DC signal and enable DC to pass through to the antenna port. The unit is housed in a single rack-mounted 19" by 1U assembly and can be used with other CCI products for further sector enhancement. Outdoor packaging can be provided. Typical deployment uses two identical units per sector, enabling Tx/Rx from both operator BTS ports to combine onto 2 main feeder lines. Technical Description: Internal duplexers deliver signal to independent Tx and Rx filter combiners with ceramic resonators, 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. |
