SA18N50W-10

Attenuators Overview

The SA18N50W-10 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It provides a nominal attenuation of 10 dB with a 50 Ohm impedance. The device features N-type connectors, specifically a male plug on one end and a female jack on the other. It is rated for a continuous power handling capacity of 50 Watts. The unit exhibits a Voltage Standing Wave Ratio (VSWR) of 1.6:1. It operates within a temperature range from -55°C to +125°C and utilizes a heatsink body construction.

Attenuators Feature Summary

• Provides precise 10 dB signal attenuation across a wide frequency spectrum extending to 18 GHz.
• Engineered with a robust heatsink body structure to manage thermal loads at high power levels.
• Features standard N-type connector interfaces ensuring compatibility with common RF systems.

Attenuators Applications

• High-power RF test and measurement setups requiring stable signal reduction.
• Integration into microwave communication systems operating at elevated power levels.
• Laboratory environments demanding reliable attenuation components with broad bandwidth coverage.

Attenuators Procurement Notes

Verify the specific model designation against official Fairview Microwave documentation to ensure accuracy, as distributor listings may contain variations or errors. Confirm that the 50 Watt power rating and 18 GHz frequency limit align with your system requirements before finalizing procurement. Cross-reference the connector configuration to ensure it matches the required male-to-female interface for your application.

Attenuators Selection Notes

Select this component when a 10 dB attenuation value is required in a system capable of handling 50 Watts of continuous power. Ensure the operational environment falls within the specified -55°C to +125°C temperature range. Verify that the N-type connector interface is compatible with existing cabling and equipment. Consider the physical dimensions and weight associated with the heatsink design during mechanical integration planning.

Attenuators Part Context

This part belongs to the Fairview Microwave series of connectorized attenuators. It is distinct from lower power variants like the SA18N-10 or higher power models such as the SA18NMNF25W-10. The specific suffix indicates its power handling capability and connector type within the broader product line.

Attenuators Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include FMAT7604-10, SA18NFNF50W-10, and SA18NFNM50W-10 from Fairview Microwave. Other potential equivalents listed include BW-N10W50+ and 3082-7550-18-10 from Amphenol XMA. Verify electrical specifications match exactly before substitution.
