SA18N5WA-40

Attenuators Overview

The SA18N5WA-40 is a fixed coaxial attenuator manufactured by Fairview Microwave. It provides a nominal attenuation of 40 dB with a maximum frequency range extending to 18 GHz. The component features N-type connectors, specifically a male plug to female jack configuration. It is rated for 5 watts of continuous power and maintains a VSWR of 1.35:1. The unit operates within a temperature range of -65°C to +125°C and utilizes a passivated stainless steel body.

Attenuators Feature Summary

• Provides precise signal reduction via a fixed 40 dB attenuation value
• Supports high-frequency operations up to 18 GHz with stable impedance
• Constructed with a durable passivated stainless steel housing for thermal management

Attenuators Applications

• RF signal path power level control in test and measurement equipment
• Attenuation stages in wireless communication system architectures
• Signal conditioning within microwave circuit board assemblies

Attenuators Procurement Notes

Verify the specific connector gender combination matches the application requirements before purchase. Confirm that the 5-watt power rating aligns with the peak and average power levels present in the target RF circuit. Ensure the operating temperature environment falls within the specified -65°C to +125°C range to maintain performance integrity and prevent damage to the internal resistive elements.

Attenuators Selection Notes

Select this model when a high attenuation value of 40 dB is required at frequencies up to 18 GHz. Choose this variant over higher power ratings if the system power levels remain below 5 watts. Consider the N-type interface compatibility with existing cable assemblies and fixture hardware. Evaluate the physical dimensions and mounting requirements against available space constraints in the assembly.
