SA18N5WA-20

Attenuators Overview

The SA18N5WA-20 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It provides a nominal attenuation of 20 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 5 Watts. The unit incorporates a black aluminum heatsink body to manage thermal dissipation effectively. The operating temperature range extends from -55°C to +125°C, ensuring reliability in diverse environments.

• Protection of sensitive receiver inputs in high-power scenarios

Attenuators Procurement Notes

Verify the specific datasheet version for the SA18N5WA-20 to confirm current manufacturing status and detailed electrical tolerances. Ensure that the 5-watt power rating aligns with your system's peak and average power requirements. Confirm connector gender compatibility before integration. Check for any RoHS compliance documentation if required for your project specifications.

Attenuators Selection Notes

Select this component when a 20 dB attenuation value is required within an 18 GHz bandwidth. The 5-watt power rating suits moderate power levels but may be insufficient for high-power transmission lines compared to higher-rated models like the 50W variants. The N-type interface dictates compatibility with standard N-series cabling and equipment. Consider the physical dimensions and heatsink design for mounting constraints.

Attenuators Part Context

This part belongs to Fairview Microwave's series of connectorized fixed attenuators. These components are engineered to provide precise signal attenuation without significant reflection. The SA18N5WA-20 utilizes a robust construction suitable for both laboratory and field applications. It represents a standard solution for managing signal strength in coaxial RF circuits requiring N-type interconnects.

Attenuators Replacement Considerations

Direct parameter-equivalent substitutes include the SA18NMNF25W-20, which offers similar attenuation and frequency range but with a higher 25-watt power rating and different connector orientation. Other potential replacements within the same family include the SA18N5WA-10 for lower attenuation needs. Always verify mechanical fit and electrical performance against the original specification.
