BW-S3W5+

Attenuators Overview

The BW-S3W5+ is a precision fixed attenuator manufactured by Mini-Circuits, designed for high-frequency RF applications. It provides a nominal attenuation of 3 dB across a frequency range from DC to 18 GHz. The component operates with a characteristic impedance of 50 Ohms and supports a maximum power handling capacity of 5 Watts. It utilizes SMA Female to SMA Male connectors housed in the DC737 case style. Typical performance data indicates insertion loss values ranging from approximately 2.81 dB at 100 MHz to 2.91 dB at 6 GHz, ensuring consistent signal reduction within specified tolerances.

Attenuators Feature Summary

• Provides precise 3 dB attenuation across a wide DC to 18 GHz bandwidth
• Supports high power handling up to 5 Watts for robust operation
• Features SMA Female to SMA Male coaxial interface for reliable connectivity

Attenuators Applications

• RF instrumentation systems requiring signal level adjustment
• Impedance matching networks in microwave circuits
• Test and measurement equipment signal conditioning

Attenuators Procurement Notes

Verify the specific datasheet version provided by Mini-Circuits or authorized distributors to confirm current manufacturing status and compliance certifications. Ensure that the SMA connector orientation and DC737 package dimensions align with your assembly requirements. Cross-reference part numbers carefully as suffixes may indicate variations in packaging or testing standards rather than functional changes.

Attenuators Selection Notes

Select this component when a stable 3 dB attenuation is required up to 18 GHz with 5 Watt power handling. Consider the SMA interface compatibility with existing circuit board layouts or cable assemblies. Evaluate thermal management needs based on the continuous power rating and ensure the operating environment stays within the specified temperature range for optimal performance stability.

Attenuators Part Context

This model belongs to the BW series of coaxial precision fixed attenuators from Mini-Circuits. These components are engineered for consistency and reliability in demanding RF environments. The series offers various attenuation values and connector configurations, with the BW-S3W5+ specifically addressing mid-range attenuation needs with high power capability.

Attenuators Replacement Considerations

Direct substitutes include other Mini-Circuits models with identical 3 dB attenuation, 5W power rating, and SMA interfaces such as BW-S3+. Verify that alternative parts match the DC-18 GHz frequency range and 50 Ohm impedance specifications to maintain system integrity without redesigning surrounding circuitry.
