Microlab CM-14 series hybrid combiners have been designed for LTE-LAA deployments. The CM-14 series now covers an ultra-wide bandwidth of 350 – 5,925 MHz. They are most commonly used to combine up to four wireless carriers in the operating band to single or multiple antenna feeds or distribution cables. Unused input and output ports should be terminated with low PIM loads.

Return loss and isolation have been optimized while passive intermodulation (PIM) is minimized. Input and output connectors have been separately grouped for convenient connection and each connector is spaced to allow controlled wrench tightening of connectors. Also available in rack mount chassis as CM-R14.
