R411804121

Overview

The Radiall USA, Inc. R411804121 is a connectorized attenuator designed for RF applications. It features an SMA male-to-male inline configuration with a 50-ohm impedance. The component provides a nominal attenuation of 4 dB and operates within a frequency range of 0 Hz to 18 GHz. It is rated for a maximum power handling capacity of 2 watts. The device utilizes a brass base material with nickel plating and gold-plated center contacts, ensuring reliable signal integrity in high-frequency environments.

Feature Summary

• SMA male-to-male inline connectorized design
• Nominal 4 dB attenuation value
• Operates up to 18 GHz frequency range
• 2W power handling capability

Applications

Procurement Notes

Verify the specific SMA connector gender and mating interface compatibility with existing circuitry before integration. Confirm that the 2W power rating aligns with the peak signal levels in the target application to prevent thermal damage. Ensure the operating temperature range meets environmental requirements. Cross-reference the datasheet for precise mechanical dimensions and mounting constraints.

Selection Notes

Select this component when a fixed 4 dB attenuation is required in an SMA-based system. Consider the 18 GHz upper frequency limit for high-speed signal processing needs. Evaluate the 2W power handling against expected signal loads. Compare with other attenuators if variable attenuation or different connector types are necessary for the specific design constraints.
