The 4x4 Hybrid is a matrix of Hybrid Couplers arranged so that signals applied to any of the four inputs will be split equally between the four outputs. This allows 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 output ports must be terminated externally in 50W, with an appropriate PIM performance. Note that the phase relationship of the outputs in this model is not consistent.
Special attention has been directed to maximize isolation in the wireless bands and minimize passive intermodulation (PIM). Unit also available with 7-16 DIN or N connectors as part of the CM-x8D or CM-x8N series.
