SA01B-20

Attenuators Overview

The SA01B-20 is a fixed attenuator manufactured by Fairview Microwave, designed for signal conditioning applications. It provides a nominal attenuation of 20 dB with a frequency range extending up to 1 GHz. The component operates at a rated power of 0.5 Watts and maintains a VSWR of 1.25. It features a 50 Ohm impedance system and utilizes BNC connectors, specifically a male plug on one end and a female jack on the other. The housing is constructed from brass with a tri-metal finish.

Attenuators Feature Summary

• Provides precise 20 dB signal attenuation within the specified frequency band
• Utilizes robust brass construction with tri-metal body plating for durability
• Ensures low reflection through a stable 1.25 VSWR rating

Attenuators Applications

• RF signal level reduction in test and measurement setups
• Impedance matching and protection in 50 Ohm coaxial systems
• Signal conditioning for BNC-based instrumentation

Attenuators Procurement Notes

Verify connector gender configuration matches the design requirement, as this model specifies a male plug to female jack arrangement. Confirm that the 0.5 Watt power rating aligns with the maximum expected signal levels in the application circuit to prevent thermal damage. Ensure the operating frequency does not exceed 1 GHz to maintain the specified 20 dB attenuation accuracy and VSWR performance.

Attenuators Selection Notes

Select this component when a fixed 20 dB reduction is required for low-power signals below 1 GHz. The BNC interface makes it suitable for legacy or standard benchtop equipment. Consider the 0.5 Watt limit carefully; higher power applications require models with heatsink bodies or higher wattage ratings. The brass tri-metal body offers corrosion resistance suitable for general laboratory environments.

Attenuators Part Context

This part belongs to the series of fixed coaxial attenuators produced by Fairview Microwave. These components are categorized under signal conditioning hardware used to manage RF energy levels. The product line typically includes various attenuation values and connector types, serving as passive elements to protect sensitive downstream devices or adjust signal strength for accurate measurement.

Attenuators Replacement Considerations

Direct substitutes must match the 20 dB value, BNC interface, and 1 GHz frequency limit. Equivalent parts from other manufacturers should be verified for identical 50 Ohm impedance and comparable VSWR specifications. Ensure the replacement also supports the 0.5 Watt power handling capability if the original design constraints remain unchanged.
