SA18N100-40

Attenuators Overview

The SA18N100-40 is a fixed attenuator manufactured by Fairview Microwave, designed for high-power RF applications. It provides a nominal attenuation of 40 dB and operates from DC to 18 GHz. The device features N male (plug) to N female (jack) connectors and is rated for up to 100 watts of power. It utilizes a heatsink body for thermal management and maintains a VSWR of 1.6.

Attenuators Feature Summary

• Directional attenuation design for precise signal control
• High power handling capability with integrated heatsink body
• Broadband operation covering DC to 18 GHz frequency range

Attenuators Applications

• RF test and measurement setups requiring high isolation
• Signal conditioning in high-power transmission lines
• Attenuation stages in radar and communication systems

Attenuators Procurement Notes

Verify the specific datasheet version for the SA18N100-40 to confirm current manufacturing status and detailed electrical tolerances. Ensure that the connector gender and interface type match the system requirements exactly. Check for any regional distribution restrictions or supply limitations before finalizing procurement plans.

Attenuators Selection Notes

Select this component when a 40 dB fixed attenuation value is required within an 18 GHz bandwidth. The 100-watt power rating and heatsink construction make it suitable for high-energy environments where standard attenuators might overheat. Ensure the N-type connector compatibility aligns with existing cable assemblies.

Attenuators Part Context

This part belongs to Fairview Microwave's series of connectorized attenuators. It shares the same physical connector interface and general form factor as other models in the SA18N100 series, differing primarily in attenuation value and specific internal resistor configuration.

Attenuators Replacement Considerations

Direct substitutes include the SA18N100-03, SA18N100-06, and SA18N100-10, which share identical connector types, power ratings, and frequency ranges but offer different attenuation values. Verify that the system can tolerate the alternative attenuation levels.
