BW-S1W2+

Attenuators Overview

The BW-S1W2+ is a coaxial precision fixed attenuator manufactured by Mini-Circuits, designed for RF and microwave applications. It provides a nominal attenuation of 1 dB with a typical VSWR of 1.20. The component operates over a frequency range from DC to 18,000 MHz (18 GHz) and supports a power handling capacity of 2 Watts. It features stainless steel SMA male and female connectors, ensuring reliable in-line module integration. The device is rated for an operating temperature range of -55°C to +100°C, making it suitable for demanding environments requiring stable signal attenuation across wide bandwidths.

Attenuators Feature Summary

• Provides precise fixed attenuation with excellent voltage standing wave ratio performance
• Features stainless steel SMA male and female connectors for robust interconnection
• Operates reliably within a wide temperature range of -55°C to +100°C

Attenuators Applications

• Signal matching in RF circuits
• Calibration and measurement instrumentation
• Test set-ups requiring precise signal level reduction

Attenuators Procurement Notes

Verify the specific datasheet version and manufacturer specifications before procurement to ensure compliance with required electrical parameters. Confirm that the SMA connector polarity and mechanical dimensions match the intended PCB or cable assembly design. Check for RoHS compliance status if environmental regulations apply to the final product. Ensure the power rating of 2 Watts is sufficient for the maximum expected signal levels in the application to prevent thermal damage.

Attenuators Selection Notes

Select this component when a low-loss, high-precision attenuation value is required up to 18 GHz. The 2-watt power handling capability makes it suitable for moderate power applications where standard attenuators might overheat. Consider the SMA interface compatibility with existing system infrastructure. The wide operating temperature range allows for deployment in harsh industrial or outdoor environments without derating concerns.

Attenuators Part Context

The BW-S1W2+ belongs to Mini-Circuits' BW series of precision fixed attenuators. This series is characterized by high accuracy and stability across broad frequency bands. Similar parts in the lineup include the BW-S7W2+ and BW-S30W5, which offer different attenuation values and power ratings. These components are widely used in communication systems, radar, and test equipment where signal integrity and precise control are critical.

Attenuators Replacement Considerations

Direct substitutes may include other Mini-Circuits models with identical 1 dB attenuation and SMA interfaces, such as those in the BW-S series. Verify that any replacement maintains the same 2-watt power rating and 18 GHz frequency limit. Cross-check connector gender and thread specifications to ensure mechanical compatibility. Alternative manufacturers may offer comparable performance but require validation of VSWR and temperature specs.
