SA18N50W-40

Attenuators Overview

The SA18N50W-40 is a fixed attenuator manufactured by Fairview Microwave, designed for RF applications up to 18 GHz. It provides a nominal attenuation of 40 dB with a maximum VSWR of 1.5. The device features N-type connectors, specifically a male plug on one end and a female jack on the other. It is rated for a power handling capacity of 50 Watts and utilizes a heatsink body for thermal management. The unit operates within a temperature range of -65°C to +125°C and maintains a 50 Ohm impedance.

Attenuators Feature Summary

• High-power dissipation capability via integrated heatsink body construction
• Broadband frequency operation extending from DC to 18 GHz
• Robust mechanical interface using N-type male plug to female jack configuration

Attenuators Applications

• RF signal level reduction in high-power transmission lines
• Test and measurement setups requiring precise attenuation at microwave frequencies
• Protection of sensitive receiver inputs from high-power sources

Attenuators Procurement Notes

Verify the specific connector gender configuration against project requirements, as variations exist within the series. Confirm that the 50-watt power rating aligns with peak and average power levels in the intended circuit. Ensure environmental conditions remain within the specified -65°C to +125°C operating range to maintain performance integrity and prevent thermal damage.

Attenuators Selection Notes

Select this component when high attenuation values are required alongside significant power handling capabilities. The N-type interface offers durability and reliable performance at higher frequencies compared to smaller connectors. Consider the physical dimensions and mounting requirements associated with the heatsink body design during system integration planning.
