BW-S40W5+ is listed in the Attenuators range at ChipApex. The manufacturer field lists Mini-Circuits. Its product description is FXD ATTEN / SMA / 40DB 5W ROHS. Review the specifications below when checking this part for your BOM.
The BW-S40W5+ is a fixed attenuator from Mini-Circuits designed for RF applications. It provides a nominal attenuation of 40 dB with a maximum measured value of 40.12 dB across a frequency range of 0 Hz to 18 GHz. The component features SMA connectors in a male/female configuration and operates at a 50 Ohm impedance. It supports a power rating of 5 W and functions within a temperature range of -55°C to +100°C. The unit measures 30.48 mm in length and belongs to the BW series.
Verify the specific datasheet revision and product change notifications prior to procurement, as Mini-Circuits may issue updates affecting performance or compliance status. Confirm that the SMA connector gender and physical dimensions align with the target PCB or cable assembly requirements. Ensure the operating environment remains within the specified -55°C to +100°C thermal limits to maintain rated power handling capabilities.
Select this model when a precise 40 dB attenuation is required up to 18 GHz with SMA interface compatibility. Consider the 5 W power rating for high-power applications, ensuring thermal management is adequate. Compare against the BW-N40W5+ if N-type connectors are preferred for higher mechanical durability or different mating constraints.
This component is part of the BW series of connectorized attenuators manufactured by Mini-Circuits. The series offers various attenuation values and connector types for RF and microwave designs. The BW-S40W5+ specifically addresses needs for high-frequency signal control using standard SMA interfaces, fitting into broader system architectures requiring stable attenuation characteristics.
The BW-N40W5+ serves as a direct functional substitute offering identical electrical specifications but utilizes N-type connectors instead of SMA. This alternative is suitable when higher mechanical robustness or different mating hardware is required without changing the circuit's electrical performance.
The maximum operating frequency is 18 GHz.
Yes, the frequency range starts at 0 Hz, allowing for DC operation.
