Microlab FZ series of fixed Coaxial Attenuators is designed for high
power wireless applications where low, guaranteed PIM performance is
critical. Standard models, except 3 dB, are unidirectional with a conven-
tional 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 ter-
mination. Other connector configurations are available to special order.
The design is exceptionally rugged, and negligibly affected by
changes in ambient temperature. Low PIM Attenuators with power rat-
ings 10W are available as the FY series.
