The model CA-44N hybrid coupler has exceptional 30 dB isolation, making it suitable for combining any two signals over the frequency band from 800 to 2200 MHz. It has been designed to meet the special needs of the wireless market and is most commonly used to combine two wireless carriers up to 200 W, to a single antenna feed or distribution cable. This requires the termination of one output port in 50 W and results in a 3 dB loss in each signal. In situations where two similar feeds are required, such as in an in-building application, both outputs may be used eliminating the 3 dB loss and the need for a termination. Special attention has been directed to maximize isolation and minimize passive intermodulation. Mechanically units are moisture sealed for outside applications, and have hex-style N connectors, spaced to allow controlled wrench tightening.
