SA18NFNF50W-10

Attenuators Overview

The SA18NFNF50W-10 is a fixed RF attenuator manufactured by Fairview Microwave, designed for interconnect applications. It provides a nominal attenuation of 10 dB with a frequency range extending from 0 Hz to 18 GHz. The component features N-type connectors, specifically female-to-female configuration, and operates at a standard impedance of 50 Ohms. It is rated for a maximum power handling capacity of 50 Watts and includes a heatsink body for thermal management. The Voltage Standing Wave Ratio (VSWR) is specified at 1.6.

Attenuators Feature Summary

• High-power handling capability up to 50 Watts with integrated heatsink body
• Broadband operation covering DC to 18 GHz frequency range
• Directional design utilizing N-type female-to-female connectors

Attenuators Applications

• High-power RF signal testing and measurement systems
• Telecommunications infrastructure requiring significant signal reduction
• Radio frequency circuit development and validation

Attenuators Procurement Notes

Verify the specific connector gender configuration against project requirements, as datasheets may list variations such as male-to-female or female-to-female for similar part numbers. Confirm that the 50-watt power rating aligns with peak signal levels in the application. Ensure the 18 GHz frequency limit meets system bandwidth needs. Check current supply status as availability may be restricted in certain regions.

Attenuators Selection Notes

Select this model when high power dissipation is critical, distinguishing it from lower-rated variants like the 2-watt SA18N-10. The female-to-female interface is suitable for connecting two male-ended cables or devices. Consider the physical dimensions and weight due to the heatsink construction compared to compact versions. Ensure the directional characteristic is required for the specific signal path analysis.

Attenuators Part Context

This component belongs to the Fairview Microwave SA18 series of connectorized attenuators. It shares the same frequency range and connector type as other models in the line but differs significantly in power rating and physical construction. Higher wattage ratings necessitate larger heatsink bodies, impacting size and weight compared to standard passivated steel versions.

Attenuators Replacement Considerations

The SA18NMNF50W-10 serves as a substitute if a male-to-female connection is required instead of female-to-female. For lower power applications, the SA18N-10 offers a smaller form factor but only supports 2 watts. Verify that any replacement maintains the 18 GHz upper frequency limit and 50 Ohm impedance.
