Microlab FZ Series fixed Coaxial Attenuators are designed for high power wireless applications where guaranteed low PIM performance is critical. Standard models, except 3 dB, are unidirectional with a conventional male input feeding to a female output on the opposite face of the attenuators with no though DC path. The 3 dB Attenuator has all female connectors, and also provides DC continuity by selecting input B, while selecting input A, the path is DC isolated. The unused port must be terminated with the supplied 2W termination. Other connector configurations are available to special order. The design is exceptionally rugged, and negligibly affected by changes in ambient temperature.
