SA18NFNF25W-03

Attenuators Overview

The SA18NFNF25W-03 is a fixed attenuator manufactured by Fairview Microwave, designed for radio frequency applications up to 18 GHz. It features N-type female connectors on both ends and provides a nominal attenuation of 3 dB. The unit is rated for continuous power handling of 25 Watts and maintains a Voltage Standing Wave Ratio (VSWR) of 1.6. Constructed with a heatsink body, it operates within a temperature range of -55°C to +125°C. The component has a length of 114.3 mm and weighs approximately 362.874 grams.

Attenuators Feature Summary

• Incorporates a heatsink body for thermal management during high-power operation
• Provides stable 3 dB signal attenuation across the specified frequency range
• Features N-type female connectors for secure interconnection

Attenuators Applications

• RF signal level reduction in communication systems
• Test and measurement equipment calibration
• Signal conditioning in microwave circuits

Attenuators Procurement Notes

Verify the specific connector gender configuration matches the application requirements, as this model utilizes female-to-female interfaces. Confirm that the 25 Watt power rating and 18 GHz frequency limit align with system specifications. Ensure environmental conditions remain within the stated operating temperature range to maintain performance integrity.

Attenuators Selection Notes

Select this component when N-type female connections are required for fixed attenuation. Consider the physical dimensions and weight if space constraints exist. Evaluate the VSWR specification against system reflection tolerance requirements. Verify compatibility with existing RF infrastructure before integration.

Attenuators Part Context

This part belongs to the series of connectorized attenuators produced by Fairview Microwave. These components are engineered for reliable performance in RF environments. The product line includes various attenuation values and connector types to suit different system architectures. This specific model focuses on mid-range power handling with standard N-type interfaces.

Attenuators Replacement Considerations

Cross-reference models such as SA18N100-03 for higher power ratings or SA18NMNF25W-03 for mixed connector genders. Ensure substitute parts match the 3 dB attenuation value and 18 GHz frequency capability. Verify that alternative components support the required 25 Watt power handling and similar VSWR characteristics.
