The 4x4 Hybrid is a matrix of four 3 dB Hybrid Couplers arranged so that signals applied to any of the four inputs will be split equally between the four outputs. This allows simple combining of multiple signals in the same wireless band to a common feeder cable, as might be required in a neutral host in-building distributed antenna system. Unused ports must be terminated externally in 50Ω. Special attention has been directed in these versions to maximize isolation across the wireless bands and minimize passive intermodulation (PIM). Mechanically, all inputs are on one side of the box and the outputs on the opposite face, for simple connection into the DAS distribution system. (9/08)
