R411802119

Overview

The R411802119 is a fixed RF attenuator manufactured by Radiall USA, Inc. It features an SMA male in-line module configuration with a 50-ohm impedance. The component provides a nominal attenuation of 2 dB and operates within a frequency range of 0 Hz to 8 GHz. It is rated for a maximum power handling capacity of 2 watts. The unit utilizes a bulk packaging format and is designed for direct integration into coaxial signal paths.

Feature Summary

• SMA male in-line module construction
• Fixed 2 dB attenuation value
• Operates up to 8 GHz frequency range
• 2-watt power handling capability

Applications

• RF signal level adjustment
• Impedance matching networks
• Test and measurement equipment
• Communication system calibration

Procurement Notes

Verify the specific frequency rating against application requirements, as some sources indicate variations up to 12.4 GHz. Confirm the SMA connector gender matches the circuit design. Check current availability status through authorized distributors, as stock levels may fluctuate. Ensure the 2W power rating exceeds the maximum expected signal power in the deployment environment.

Selection Notes

Select this component when a precise 2 dB reduction is required in an SMA-based 50-ohm system. Consider the 8 GHz bandwidth limit for high-frequency applications. Evaluate thermal management needs given the 2W power rating. Compare against other attenuation values if signal loss requirements differ from the fixed 2 dB specification provided by this part number.

Part Context

This part belongs to the Radiall series of connectorized attenuators. It serves as a passive interconnect device used to control signal amplitude without introducing significant distortion. The SMA interface ensures compatibility with standard coaxial cabling and test fixtures commonly found in electronics manufacturing and engineering labs.

Replacement Considerations

R411800119 offers similar SMA in-line construction but provides 0 dB attenuation. R411805000 is another option with 5 dB attenuation and a higher 15 GHz frequency range. Verify that substitute parts maintain the required 50-ohm impedance and physical form factor for direct replacement.
