SA18H-08

Attenuators Overview

The SA18H-08 is a fixed attenuator from Fairview Microwave, designed for signal management in RF systems. It provides an attenuation value of 8 dB with a frequency range extending up to 18 GHz. The component features SMA connectors, specifically a male plug on one end and a female jack on the other. It is rated for a maximum power handling capacity of 2 Watts and maintains a Voltage Standing Wave Ratio (VSWR) of 1.35:1. The unit utilizes a passivated stainless steel body and operates within a temperature range of -54°C to +125°C.

Attenuators Feature Summary

• Provides precise 8 dB signal attenuation across a wide bandwidth up to 18 GHz
• Features SMA male-to-female connector interface for standard interconnect compatibility
• Constructed with a passivated stainless steel body for durability and corrosion resistance
• Supports continuous power levels up to 2 Watts with stable impedance matching

Attenuators Applications

• RF test and measurement setups requiring specific signal reduction
• Microwave communication systems operating within the 18 GHz spectrum
• Laboratory environments for calibrating high-frequency equipment
• Signal conditioning in radar and electronic warfare applications

Attenuators Procurement Notes

Verify the exact part number SA18H-08 against official Fairview Microwave documentation to ensure correct specifications. Confirm that the SMA gender configuration matches your system requirements. Check for RoHS compliance status if environmental regulations apply to your deployment. Ensure the 2 Watt power rating is sufficient for your operational environment to prevent component damage.

Attenuators Selection Notes

Select this model when an 8 dB fixed attenuation value is required at frequencies up to 18 GHz. The SMA interface makes it suitable for general-purpose RF connections. Consider the 2 Watt power limit and 1.35 VSWR performance metrics for system integration. The passivated stainless steel construction offers robustness for various industrial and laboratory settings.

Attenuators Part Context

This component belongs to the SA18H series of connectorized attenuators manufactured by Fairview Microwave. The series is characterized by SMA interfaces and operation up to 18 GHz. Different models in the series vary primarily by their attenuation values, such as 3 dB, 6 dB, or 10 dB options, while maintaining similar physical and electrical characteristics like the 2 Watt power rating and stainless steel housing.

Attenuators Replacement Considerations

Direct substitutes may include other SA18H series models with different attenuation values if the specific 8 dB requirement can be adjusted. Cross-brand equivalents must match the SMA gender, 18 GHz frequency limit, and 2 Watt power rating. Verify that any replacement maintains the 1.35 VSWR specification to ensure signal integrity in sensitive RF paths.
