SA18N5W-03

Attenuators Overview

The SA18N5W-03 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It provides a nominal attenuation of 5 dB with a 50 Ohm impedance. The device features N-type connectors in a plug-to-jack configuration. It is rated for a power handling capacity of 5 Watts and maintains a Voltage Standing Wave Ratio (VSWR) of 1.4. The unit operates within a temperature range of -65°C to +125°C and is packaged in a bag.

Attenuators Feature Summary

• Fixed 5 dB attenuation value for signal level control
• Operational frequency range extending from DC to 18 GHz
• N-type male to female connector interface
• Heatsink body construction for thermal management

Attenuators Applications

• RF test and measurement setups requiring precise signal reduction
• Communication systems operating within the specified frequency band
• Instrumentation circuits needing impedance matching and attenuation

Attenuators Procurement Notes

Verify the specific datasheet version for the SA18N5W-03 to confirm mechanical dimensions and material specifications. Ensure that the 5 Watt power rating aligns with system peak power requirements. Confirm connector gender compatibility during integration. Check for RoHS compliance status if environmental regulations apply to the deployment environment.

Attenuators Selection Notes

Select this component when a 5 dB attenuation value is required at frequencies up to 18 GHz. The N-type interface suits applications needing robust connections. Consider the 5 Watt power rating against expected signal levels. The heatsink design supports higher power dissipation compared to standard passive units. Verify VSWR performance meets system reflection limits.

Attenuators Part Context

This part belongs to the Fairview Microwave SA18 series of connectorized attenuators. The series offers various attenuation values and connector types. The SA18N5W-03 specifically utilizes N-type connectors and a 5 dB resistive network. It is distinct from SMA or other connector variants in the same frequency range family.

Attenuators Replacement Considerations

SA18N5WA-10 is a listed related part number but differs in attenuation value and potentially connector style. Direct substitution requires verifying identical electrical parameters and mechanical fit. No other direct substitute part numbers are confirmed in public documentation.
