Microlab Model Hybrid Couplers have been designed to meet the special needs of the wireless market. They are most commonly used to combine two wireless carriers in the operating band to a single antenna feed or distribution cable. This requires the termination of one output port in 50W and results in a 3 dB loss in each signal. In situations where two similar feeds are required, as required for an in-building application, both outputs may be used eliminating the need for a termination and the 3 dB loss. For low PIM terminations see TK-20 series.
This CA-14 series, which now incorporates the wider frequency range of the CA-13 series, has been designed for systems requiring signal combining over all the wireless bands from 350 to to 5,925 MHz. Isolation has been maximized and passive intermodulation (PIM) minimized.
