R411830121

Attenuators Overview

The R411830121 is a fixed coaxial attenuator manufactured by Radiall USA, Inc. It utilizes an SMA connector interface with a 75-ohm impedance characteristic. The component provides a nominal attenuation value of 30 dB and operates within a frequency range extending from DC to 18 GHz. It is rated for a maximum power handling capacity of 2 watts. The device is designed for reliable signal level reduction in high-frequency RF applications.

Attenuators Feature Summary

• Provides precise 30 dB signal attenuation for RF systems
• Supports operation up to 18 GHz frequency range
• Engineered for 2W power handling capability
• Features 75-ohm impedance matching via SMA interface

Attenuators Applications

• RF signal level adjustment in communication systems
• Test and measurement equipment calibration
• High-frequency circuit protection and isolation

Attenuators Procurement Notes

Verify the specific impedance requirement (75 ohms) against system design specifications, as standard variants often differ. Confirm that the 2W power rating aligns with peak operational loads. Ensure SMA connector compatibility with existing cable assemblies. Check manufacturer documentation for environmental operating limits and mounting requirements prior to integration.

Attenuators Selection Notes

Select this component when a fixed 30 dB attenuation is required at 75-ohm impedance. Consider the 18 GHz upper frequency limit for bandwidth needs. Evaluate the 2W power handling against system thermal constraints. Compare against variable attenuators if adjustable levels are necessary. Verify SMA connector gender and mating requirements for proper system integration.

Attenuators Part Context

This part belongs to Radiall's line of fixed coaxial attenuators. It serves as a passive RF component for signal management. The SMA interface ensures compatibility with standard connectors. The 75-ohm specification distinguishes it from common 50-ohm variants. It supports high-frequency performance up to 18 GHz.

Attenuators Replacement Considerations

Cross-reference with other Radiall SMA 75-ohm 30 dB attenuators. Verify identical frequency range (DC-18 GHz) and power rating (2W). Ensure mechanical dimensions and connector gender match. Check for equivalent VSWR performance metrics.
