SA18NFNM50W-50

Attenuators Overview

The SA18NFNM50W-50 is a fixed RF attenuator manufactured by Fairview Microwave, designed for high-power applications up to 50 Watts. It provides a nominal attenuation of 50 dB with a maximum frequency range extending to 6 GHz. The component features N-type connectors, configured as Female (Jack) on one end and Male (Plug) on the other, facilitating directional signal reduction in 50 Ohm systems. It incorporates a heatsink body to manage thermal dissipation and maintains a Voltage Standing Wave Ratio (VSWR) of 1.3.

Attenuators Feature Summary

• Directional signal attenuation capability within specified frequency limits
• High power handling rated at 50 Watts for robust operation
• Integrated heatsink body structure for effective thermal management
• Mixed gender connector interface combining N-type jack and plug

Attenuators Applications

• RF signal level reduction in communication test setups
• Power monitoring and measurement circuit protection
• Signal conditioning in microwave transmission lines
• Attenuation stages in radar system testing environments

Attenuators Procurement Notes

Verify the specific datasheet version to confirm exact mechanical dimensions and material specifications. Ensure compatibility with existing N-type mating hardware regarding torque ratings and surface finish. Confirm that the 6 GHz upper frequency limit meets system requirements, as some similar models may extend higher. Check for any specific handling instructions related to the heatsink construction during installation.

Attenuators Selection Notes

Select this model when a 50 dB attenuation value is required alongside mixed gender N-type connectivity. The 50 Watt power rating distinguishes it from lower-power variants suitable for standard laboratory use. Consider the 6 GHz bandwidth constraint against widerband alternatives if frequencies exceed this threshold. The heatsink design makes it suitable for continuous wave applications where thermal buildup is a concern.

Attenuators Part Context

This component belongs to Fairview Microwave's series of connectorized attenuators, specifically engineered for high-power RF environments. The 'SA' prefix typically denotes fixed attenuators, while the suffix indicates connector types and power ratings. It serves as a passive interconnect device essential for maintaining signal integrity and protecting sensitive downstream components from excessive power levels in microwave circuits.

Attenuators Replacement Considerations

FMAT7604-50 is listed as a parameter-equivalent substitute. Verify connector gender configuration and VSWR specifications before substitution, as other models in the series may differ in interface type or frequency range.
