SA18NMNF50W-40

Attenuators Overview

The SA18NMNF50W-40 is a fixed RF attenuator manufactured by Fairview Microwave, designed for high-power applications up to 18 GHz. It features N-type connectors with a male plug on the input and a female jack on the output. The unit provides a nominal attenuation of 40 dB at a system impedance of 50 Ohms. It is rated for continuous power handling of 50 Watts and includes a heatsink body for thermal management. The Voltage Standing Wave Ratio (VSWR) is specified at 1.6, ensuring signal integrity across the operational frequency range from DC to 18 GHz.

Attenuators Feature Summary

• High power handling capability rated at 50 Watts for sustained operation
• Integrated heatsink body design for effective thermal dissipation
• Broadband frequency performance extending from DC to 18 GHz
• N-type connector configuration with male plug and female jack interfaces

Attenuators Applications

Attenuators Procurement Notes

Verify the specific datasheet for the SA18NMNF50W-40 to confirm current manufacturing status and detailed electrical tolerances. Ensure that the procurement channel provides official documentation regarding RoHS compliance and traceability. Confirm physical dimensions and mounting requirements align with the intended assembly constraints before finalizing acquisition.

Attenuators Selection Notes

Select this component when a 40 dB attenuation value is required within an N-type interface system operating up to 18 GHz. The 50 Watt power rating makes it suitable for high-energy signal paths where standard attenuators may overheat. Consider the heatsink form factor for integration into chassis or rack environments requiring passive cooling solutions.
