BW-S40W2+

Attenuators Overview

The BW-S40W2+ is a coaxial precision fixed attenuator manufactured by Mini-Circuits. It provides a nominal attenuation of 40 dB with an impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 18 GHz and handles a power rating of 2 Watts. It utilizes SMA connectors in an in-line module configuration, ensuring reliable signal reduction across its specified bandwidth.

Attenuators Feature Summary

• Provides precise 40 dB signal attenuation for RF applications
• Operates from DC up to 18 GHz frequency range
• Features SMA male-to-female in-line connector interface
• Supports 2 Watt power handling capacity

Attenuators Applications

• RF instrumentation systems
• Signal matching networks
• Test and measurement equipment

Attenuators Procurement Notes

Verify the exact part number suffix (+) indicates RoHS compliance when sourcing. Confirm SMA connector gender orientation matches system requirements. Ensure operating frequency does not exceed 18 GHz limit. Validate power handling needs against 2 Watt maximum rating before integration into high-power RF chains.

Attenuators Selection Notes

Select this component when a fixed 40 dB loss is required in a 50-Ohm system. The SMA interface suits standard benchtop or modular setups. Consider thermal management if continuous power approaches 2 Watts. Verify that the 18 GHz upper frequency limit meets the application's spectral requirements without significant insertion loss variation.

Attenuators Part Context

This model belongs to Mini-Circuits' BW series of coaxial precision fixed attenuators. These components are designed for stable performance across wide bandwidths. The series offers various attenuation values and connector options to suit different RF circuit architectures and impedance matching needs.

Attenuators Replacement Considerations

Direct substitutes include other Mini-Circuits models with identical 40 dB attenuation, 50 Ohm impedance, and SMA connectors, such as BW-S40+. Verify mechanical dimensions and connector polarity compatibility before substitution.
