Abstract: A modular component for interconnection with another modular component to form a remote unit of a distributed antenna system, the modular component includes: an upstream transport interface to receive downlink signals indicative of downlink radio frequency signals originating from another unit in the DAS; a central signal processor to convert the downlink signals received at the upstream transport interface into the downlink radio frequency signals; a radio frequency amplification section to amplify at least a first portion of the downlink radio frequency signals using at least a first radio frequency amplifier; and a radio frequency filtering section to: filter the at least the first portion of the downlink radio frequency signals using at least a first radio frequency filter and provide the at least the first portion of the downlink radio frequency signals to at least one antenna for transmission to at least one subscriber unit.
