BW-S2W2+

Attenuators Overview

The BW-S2W2+ is a precision fixed coaxial attenuator manufactured by Mini-Circuits, designed for high-frequency RF applications. It provides a nominal attenuation of 2 dB with a tolerance of ±0.4 dB across a frequency range from DC to 18 GHz. The component operates at a maximum power handling capacity of 2 Watts (33 dBm) and features a characteristic impedance of 50 Ohms. It utilizes SMA connectors and is housed in the FF658 case style, supporting wire, SMD, and through-hole mounting configurations.

Attenuators Feature Summary

• Precision attenuation performance with excellent VSWR characteristics
• Wideband operation spanning from DC to 18 GHz
• Robust construction using stainless steel materials

Attenuators Applications

• RF signal level control in microwave systems
• Impedance matching and termination in test equipment
• Signal conditioning in communication infrastructure

Attenuators Procurement Notes

Verify the specific datasheet revision and compliance documentation, such as RoHS and REACH status, prior to procurement. Confirm that the SMA connector interface and FF658 package dimensions align with your PCB layout or assembly requirements. Ensure the 2W power rating is sufficient for your operational environment to prevent thermal degradation.

Attenuators Selection Notes

Select this component when a stable 2 dB attenuation is required up to 18 GHz. The 50-Ohm impedance matches standard RF systems. Consider the 2W power handling limit for high-power applications. The SMA interface offers broad compatibility. Stainless steel construction ensures durability in demanding environments compared to plastic alternatives.

Attenuators Part Context

This part belongs to Mini-Circuits' BW series of precision fixed attenuators. These components are engineered for consistent performance in RF and microwave circuits. The series offers various attenuation values while maintaining low VSWR and wide bandwidth capabilities, serving as essential passive elements for signal management in electronic designs.

Attenuators Replacement Considerations

Direct substitutes within the same family include BW-S2W2 (non-plussed version). Verify connector type and power ratings when considering alternative manufacturers. Ensure replacement parts maintain the 50-Ohm impedance and 18 GHz frequency range to preserve system integrity.
