Abstract
A modular high power, low passive intermodulation, active, universal, distributed antenna system interface tray that includes one or more front-end RF frequency duplexers instead of a high power, low passive intermodulation attenuator to achieve superior FIM performance. A cable switch matrix allows for the use of the system among varying power levels* and accomplishes the above in a modular architecture.
