CM-99N

This 4 x 4 Hybrid Coupler covers the 380 – 960 MHz range of frequencies with high isolation and low passive intermodulation (PIM) in either N or 7-16 mm connectors. A similar 2 x 2 model is available as a CA-99N.
These networks provides simple combining of 2 or 4 independent signals in the specified wireless band to a common feeder cable, as might be required in a radio base station or in a neutral host in-building distributed antenna system. The unused hybrid ports must be terminated at the appropriate power rating. Note that these models use hybrid designs that are not true 90° Quadrature Hybrids.
