• Signal conditioning in microwave circuits

Procurement Notes

Verify the specific datasheet version when sourcing this component to ensure compliance with current manufacturing standards. Confirm that the SMA connector polarity and impedance match system requirements before integration. Check availability status as supply levels may fluctuate due to production cycles.

Selection Notes

Select this model when a precise 5 dB reduction is required at frequencies extending to 18 GHz. Ensure the 2 W power handling capacity aligns with the system's maximum signal output. Compare against other Radiall series options if different attenuation values or connector types are needed for the specific application design.

Part Context

This component belongs to the Radiall attenuator product line designed for interconnect applications. It serves as a passive RF element used to reduce signal amplitude without distortion. The SMA interface ensures compatibility with standard coaxial cable assemblies and test fixtures commonly used in laboratory and industrial environments.

Replacement Considerations

R411805000 offers similar specifications but operates up to 15 GHz instead of 18 GHz. Verify frequency requirements before substitution. Other models in the series provide different attenuation values such as 9 dB.
