SA18NFNF50W-40

Attenuators Overview

The SA18NFNF50W-40 is a fixed RF attenuator manufactured by Fairview Microwave, designed for interconnect applications within radio frequency systems. It provides a nominal attenuation of 40 dB across a frequency range from 0 Hz to 18 GHz. The component features N-type female connectors on both ends, facilitating inline integration into coaxial circuits. It is rated to handle up to 50 Watts of power and maintains a Voltage Standing Wave Ratio (VSWR) of 1.6. The unit incorporates a heatsink body for thermal management and is packaged individually in a bag.

Attenuators Feature Summary

• Provides fixed 40 dB signal attenuation for precise power control
• Operates effectively from DC up to 18 GHz frequency range
• Features N-type female-to-female connector configuration for direct circuit insertion
• Includes a heatsink body design to support high-power dissipation

Attenuators Applications

• Radio frequency test and measurement setups requiring signal reduction
• High-power microwave system calibration and monitoring
• Defense and aerospace communication equipment signal conditioning
• Laboratory instrumentation input protection and level adjustment

Attenuators Procurement Notes

Verify the specific datasheet version when sourcing this component to ensure compliance with current manufacturing standards. Confirm that the N-type connector gender matches the intended circuit interface requirements. Check for any updated environmental or material declarations if operating in regulated industries. Ensure the 50-watt power rating aligns with the peak and average power levels present in the application environment to prevent component damage.

Attenuators Selection Notes

Select this model when a high-power, wideband fixed attenuator is required for frequencies extending to 18 GHz. The 40 dB attenuation value suits scenarios needing significant signal reduction. The N-type interface is appropriate for larger coaxial systems where SMA or smaller connectors are unsuitable. Consider the heatsink requirement if continuous high-power operation is expected, as passive cooling relies on the body's thermal mass and surface area.

Attenuators Part Context

This part belongs to Fairview Microwave's line of connectorized attenuators, specifically designed for robust RF interconnect solutions. It complements other products in the series that offer varying attenuation values and connector types. The product targets applications demanding reliable performance in high-frequency environments, serving as a critical passive component for managing signal integrity and power levels in complex RF architectures.

Attenuators Replacement Considerations

Equivalent parts include SA18NFNF50W-30 for lower attenuation needs. Other potential substitutes may include models from manufacturers like Pasternack or Mini-Circuits offering similar N-type, 40 dB specifications up to 18 GHz. Verify mechanical dimensions and mounting requirements before substitution.
