Microlab 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 band to a single antenna feed or distribution cable. This requires the termination of one output port in 50O 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. The CA-84K Series is designed for harsh ourtdoor applications in corrosive salt fog environments. The CA-84KE has 4.3-10 female terminations and has a PIM rating of -161dBc.
