SA18N100-20

Attenuators Overview

The SA18N100-20 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It features N male (plug) to N female (jack) connectors and provides a nominal attenuation of 20 dB. The unit is rated for 100 Watts of power handling and includes a heatsink body for thermal management. Key electrical specifications include a maximum VSWR of 1.35 and a 50 Ohm impedance.

Attenuators Feature Summary

• Directional signal attenuation capability
• Heatsink body construction for thermal dissipation
• High power handling rating

Attenuators Applications

• RF test and measurement setups
• Signal level reduction in high-power transmission lines
• Protection of sensitive receiver inputs

Attenuators Procurement Notes

Verify the specific datasheet version for the SA18N100-20 to confirm the exact VSWR specification, as sources indicate values of 1.35. Ensure compatibility with N-type connector interfaces and verify that the 100 Watt power rating aligns with your system's peak power requirements before integration.

Attenuators Selection Notes

Select this component when a 20 dB fixed attenuation value is required within an 18 GHz bandwidth. The choice is driven by the need for high power handling at 100 Watts and the specific N-type connector interface. The heatsink design supports continuous operation under significant thermal load.

Attenuators Part Context

This part belongs to Fairview Microwave’s series of connectorized fixed attenuators. These components are engineered for stability and precision in RF environments. The model designation indicates the frequency range, connector type, power rating, and attenuation value.

Attenuators Replacement Considerations

Check for SA18N100-03 if 3 dB attenuation is needed instead of 20 dB. Verify connector gender and orientation against existing cabling infrastructure to ensure mechanical compatibility.
