SA18N-40

Attenuators Overview

The SA18N-40 is a fixed attenuator from Fairview Microwave, designed for RF applications up to 18 GHz. It features N-type connectors with a male plug on one end and a female jack on the other. The unit provides 40 dB of attenuation and is rated for 2 Watts of power handling. Constructed with a passivated stainless steel body, it maintains a Voltage Standing Wave Ratio (VSWR) of 1.5:1. The component operates within a temperature range of -65°C to +125°C and has a characteristic impedance of 50 Ohms.

Attenuators Feature Summary

• Fixed attenuation value of 40 dB for signal reduction
• Mixed connector configuration with N Male plug and N Female jack
• Passivated stainless steel housing for durability
• Operational frequency range extending up to 18 GHz

Attenuators Applications

• RF signal level adjustment in test and measurement setups
• Interconnecting equipment with mismatched signal strengths
• Protecting sensitive receiver inputs from high power levels

Attenuators Procurement Notes

Verify the specific connector gender combination matches the system requirement, as this model specifies an N Male plug to N Female jack interface. Confirm that the 2 Watt power rating is sufficient for the intended application environment. Ensure the operating temperature range meets the environmental conditions of the installation site. Check for RoHS compliance status if required by project specifications.

Attenuators Selection Notes

Select this component when a precise 40 dB attenuation is required at frequencies up to 18 GHz. The mixed gender connector interface facilitates direct connection between standard N-type ports without additional adapters. The stainless steel construction offers robustness for industrial or outdoor environments. Consider the 2 Watt power limit to prevent damage during high-power transmission scenarios.

Attenuators Part Context

This part belongs to the SA18 series of connectorized attenuators manufactured by Fairview Microwave. The series covers various attenuation values and connector types, all supporting operation up to 18 GHz. The SA18N-40 specifically addresses the need for high attenuation in N-type systems, distinguishing itself from lower attenuation variants within the same product family.
