SA18N25WA-10

Attenuators Overview

The SA18N25WA-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 maximum frequency range extending from 0 Hz to 18 GHz. The component features N-type connectors, specifically a male plug to female jack configuration, and operates at a standard impedance of 50 Ohms. It is rated for a power handling capacity of 25 Watts and includes a heatsink body for thermal management. The Voltage Standing Wave Ratio (VSWR) is specified at 1.35, ensuring efficient signal transmission within the designated frequency band.

Attenuators Feature Summary

• Incorporates a heatsink body structure to facilitate effective thermal dissipation during high-power operations.
• Utilizes robust N-type connector interfaces to ensure reliable mechanical and electrical connections in RF systems.
• Maintains a low VSWR specification to minimize signal reflection and preserve signal integrity across the operational bandwidth.

Attenuators Applications

• RF signal level adjustment in communication test and measurement equipment
• Attenuation insertion in microwave circuit designs requiring precise power reduction
• Signal conditioning in radar and electronic warfare systems operating within the specified frequency range

Attenuators Procurement Notes

Verify the specific connector gender configuration and power rating against system requirements before procurement. Ensure that the operating environment falls within the specified temperature limits to maintain performance stability. Confirm compliance with relevant regulatory standards such as RoHS if required for the intended application deployment.

Attenuators Selection Notes

Select this model when a 10 dB fixed attenuation value is required for N-type interconnects up to 18 GHz. Consider the 25 Watt power rating and heatsink design for applications involving significant RF power levels. Compare VSWR specifications against other models to ensure optimal signal matching for the specific circuit design needs.
