The MCC100-501 filter module supports 5 popular multiband combining with minimal RF insertion loss. In a 4-operator scenario, these could be considered for 2-sector SISO or 1-sector 2x2 MIMO. A single MCC100 subrack can house all filter combiners for an entire 4x4 MIMO application. All Radio inputs are accessible from the front. Rear interfaces are for interconnection with the wideband hybrid combiner. The MCC100 is a 6RU rack-mount enclosure that accommodates up to (8) such combiner modules. Modular Filter Combiners can be added to the Subrack for carrier/operator adds or replaced as new service bands come to market.
