1 dB Fixed Attenuator, 3 GHz, 1 Watt

Service Description

End Product

Optimize your signal levels with this precision 1 dB fixed coaxial attenuator. Designed as a bidirectional resistive PI pad, this component effectively reduces signal amplitude while maintaining high signal integrity across a frequency range from DC to 3 GHz. Housed in a durable brass body with nickel plating, it is engineered to meet rigorous RF and microwave industry specifications.

This versatile “RF pad” is an essential tool for protecting sensitive measurement equipment, preventing signal overload in receivers or detectors, and improving impedance matching between components. Its connectorized design features an N Male interface on one side and an N Female interface on the other, ensuring seamless integration into standard 50 Ohm coaxial systems.
