SA18H-17

Attenuators Overview

The SA18H-17 is a fixed attenuator from Fairview Microwave, designed for RF applications up to 18 GHz. It features a 17 dB attenuation value with a 50 Ohm impedance. The unit connects via SMA Male (Plug) to SMA Female (Jack) interfaces. It is rated for 2 Watts of power and maintains a VSWR of 1.35. Constructed with a passivated stainless steel body, it operates within a temperature range of -54°C to +125°C.

Attenuators Feature Summary

• Provides precise 17 dB signal reduction in a compact coaxial format
• Utilizes durable passivated stainless steel construction for environmental resistance
• Ensures stable signal integrity through low VSWR performance across the frequency band

Attenuators Applications

• RF test and measurement setups requiring specific signal loss
• Microwave communication systems operating at frequencies up to 18 GHz
• Signal conditioning in high-frequency electronic circuits

Attenuators Procurement Notes

Verify the exact model designation against official Fairview Microwave documentation to confirm specifications. Ensure compatibility with existing SMA connectors and system impedance requirements. Check current availability status as supply conditions may vary. Confirm that the power rating and frequency range meet the specific application needs before procurement.

Attenuators Selection Notes

Select this component when a fixed 17 dB attenuation is required within an 18 GHz bandwidth. Consider the SMA connector gender configuration for seamless integration into the signal chain. Evaluate the 2 Watt power handling capability against peak and average signal levels. The stainless steel body offers durability suitable for demanding environments compared to standard plastic alternatives.

Attenuators Part Context

This part belongs to the SA18H series of connectorized attenuators by Fairview Microwave. These components are engineered for high-frequency stability and reliable performance. The series typically includes various attenuation values while maintaining consistent electrical characteristics and mechanical robustness across different models.

Attenuators Replacement Considerations

Direct substitutes include other 17 dB fixed attenuators with SMA male-to-female interfaces and similar 18 GHz frequency ranges. Verify that alternative parts match the 50 Ohm impedance and comparable VSWR specifications to ensure circuit continuity.
