SA18N50W-20

Attenuators Overview

The SA18N50W-20 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It features N male (plug) to N female (jack) connectors with a nominal attenuation of 20 dB and a 50 Ohm impedance. The unit is rated for 50 Watts of power handling and utilizes a heatsink body construction. Key electrical specifications include a Voltage Standing Wave Ratio (VSWR) of 1.5:1. The device operates within a temperature range of -65°C to +125°C and complies with RoHS standards.

Attenuators Feature Summary

• Constructs a robust connection using N-type male plug and female jack interfaces.
• Incorporates a heatsink body design to manage thermal loads during operation.
• Maintains signal integrity through a low VSWR specification across the frequency band.

Attenuators Applications

• RF signal path attenuation in high-power transmission systems
• Test and measurement equipment requiring precise signal reduction
• Communication infrastructure operating at microwave frequencies

Attenuators Procurement Notes

Verify the specific datasheet version for the SA18N50W-20 to confirm exact physical dimensions and connector tolerances. Ensure the application environment stays within the specified -65°C to +125°C operating range. Confirm that the 50 Watt power rating aligns with peak system requirements to prevent component damage. Check for RoHS compliance documentation if environmental regulations apply to the deployment region.

Attenuators Selection Notes

Select this model when an N-type interface is required for 20 dB attenuation at 50 Ohms. The 50 Watt power rating distinguishes it from lower-power variants in the series. Consider the heatsink body for applications involving continuous high-power signals. Verify that the 1.5 VSWR meets the system's reflection coefficient requirements. Ensure the 18 GHz frequency limit covers the operational bandwidth.
