R411804119

Overview

The R411804119 is an RF attenuator manufactured by Radiall USA, Inc. It provides a fixed attenuation of 4dB with a frequency range extending from 0 Hz to 8 GHz or 12.4 GHz depending on the specific datasheet version referenced. The component operates at a nominal impedance of 50 Ohms and handles up to 2W of power. It utilizes SMA connectors in an in-line module configuration.

Feature Summary

• Fixed 4dB attenuation value
• SMA connector interface
• In-line module design

Applications

• RF signal path conditioning
• Test and measurement equipment
• Wireless communication systems

Procurement Notes

Verify the exact upper frequency limit (8 GHz vs 12.4 GHz) against the specific manufacturer datasheet for your production batch. Confirm the package type matches the required in-line module form factor. Ensure the 50 Ohm impedance aligns with system requirements. Check for RoHS compliance status if mandated by project specifications.

Selection Notes

Select this component when a precise 4dB reduction is required within the specified microwave frequency bands. The 2W power rating suits moderate power applications. The SMA interface ensures compatibility with standard coaxial test fixtures. Verify physical dimensions fit the assembly constraints before finalizing the bill of materials.

Part Context
