R411804124

Overview

The Radiall USA, Inc. R411804124 is a fixed coaxial attenuator designed for radio frequency applications. It utilizes an SMA connector interface with a 75-ohm characteristic impedance. The component provides a nominal attenuation of 4 dB and operates at a maximum frequency of 6 GHz. It is rated for a power handling capacity of 1 Watt. The device features a male-to-male inline configuration, suitable for integration into RF signal chains requiring precise signal reduction.

Feature Summary

• Provides fixed 4 dB signal attenuation in a compact inline module format
• Engineered for 75-ohm impedance systems using SMA connectors
• Supports operation up to 6 GHz with 1 Watt power rating

Applications

• RF signal chain attenuation in communication systems
• Test and measurement equipment requiring precise signal levels
• 75-ohm video or data transmission line conditioning

Procurement Notes

Verify the specific impedance requirement (75 ohms) against system specifications, as standard SMA components are often 50 ohms. Confirm that the 1 Watt power rating meets the operational thermal requirements of the application. Ensure the SMA male-to-male configuration matches the mating connectors in the assembly. Cross-reference the manufacturer part number directly with official Radiall documentation to confirm current availability and technical validity.

Selection Notes

Select this component when a fixed 4 dB reduction is required within a 75-ohm RF environment. The SMA interface ensures compatibility with standard 75-ohm coaxial cabling. Consider the 6 GHz frequency limit and 1 Watt power handling as upper bounds for system design. This model is appropriate for applications where discrete variable attenuation is unnecessary and stable, fixed loss is preferred for signal integrity.

Part Context

This component belongs to the Radiall USA, Inc. family of fixed coaxial attenuators. These devices are engineered to provide precise, stable signal loss without introducing significant reflection or distortion. The series typically offers various attenuation values and connector types to suit different RF infrastructure needs, ensuring reliable performance across defined frequency ranges.

Replacement Considerations

Substitutes must match the 75-ohm impedance, 4 dB attenuation value, and SMA male-to-male configuration. Verify that alternative models support the 6 GHz frequency range and 1 Watt power rating. Ensure physical dimensions and mounting style are compatible with the existing assembly to maintain mechanical integrity.
