BW-S40W20+

Attenuators Overview

The BW-S40W20+ is a precision fixed attenuator from Mini-Circuits, designed for high-power RF applications. It provides a nominal attenuation of 40 dB across a frequency range of DC to 18 GHz. The component features SMA male and female connectors with a 50 Ohm impedance. It is rated for a maximum power handling capacity of 20 Watts. The unit operates within a temperature range of -55°C to +100°C. Typical VSWR is specified at 1.25:1. The housing utilizes stainless steel construction for durability.

Attenuators Feature Summary

• High power handling capability suitable for demanding RF environments
• Precision attenuation performance maintained across wide bandwidth
• Robust stainless steel housing with integrated SMA connectors

Attenuators Applications

• RF instrumentation systems requiring signal reduction
• Impedance matching in microwave circuits
• Signal conditioning in test and measurement equipment

Attenuators Procurement Notes

Verify the exact part number suffix against official Mini-Circuits documentation to ensure correct power rating and connector configuration. Confirm that the required operating temperature range aligns with the specified -55°C to +100°C limits. Check for any recent product change notifications or datasheet revisions that may affect mechanical dimensions or electrical specifications before finalizing procurement orders.

Attenuators Selection Notes

Select this component when a 40 dB attenuation value is required at frequencies up to 18 GHz. Ensure the application demands a 20 Watt power rating, distinguishing it from lower-power variants like the BW-S40W5+. Verify that SMA interface compatibility exists between the attenuator and connected transmission lines. Consider the physical size constraints as the unit measures approximately 30.48 mm in length.

Attenuators Part Context

This model belongs to the BW series of coaxial precision fixed attenuators manufactured by Mini-Circuits. The series offers various attenuation values and power ratings. The BW-S40W20+ specifically addresses high-power needs compared to standard low-power attenuators. It serves as a critical passive component in RF signal chains where precise level control is necessary without introducing significant reflection.

Attenuators Replacement Considerations

Direct substitutes include other Mini-Circuits models with identical 40 dB attenuation and 20W power ratings, such as the BW-S40W20+ itself. Cross-manufacturer replacements require careful verification of VSWR, frequency response, and power handling capabilities to ensure system performance remains unaffected.
