BW-S4W2+

Attenuators Overview

The BW-S4W2+ is a precision fixed attenuator from Mini-Circuits designed for high-frequency RF applications. It operates over a frequency range of DC to 18 GHz with a nominal attenuation value of 4 dB. The component features a 50 Ohm impedance and supports a power handling capacity of 2 Watts. It utilizes SMA connectors, specifically combining a male and female interface within an in-line module configuration. The device ensures excellent voltage standing wave ratio (VSWR) performance, typically rated at 1.20, to minimize signal reflections.

Attenuators Feature Summary

Attenuators Procurement Notes

Verify the specific part number suffix against official Mini-Circuits documentation to ensure correct connector orientation and compliance status. Confirm that the required attenuation value and power rating align with the system design specifications before procurement. Cross-reference the datasheet for any updates regarding RoHS and REACH compliance declarations.

Attenuators Selection Notes

Select this component when a fixed 4 dB attenuation is required within a DC to 18 GHz frequency range. Ensure the application environment can accommodate the 2 Watt power handling capability. Verify that the SMA male-to-female in-line form factor fits the physical constraints of the assembly. Consider the typical VSWR specification if signal integrity is critical.

Attenuators Part Context

This component belongs to the Mini-Circuits precision fixed attenuator series, which includes various models with different attenuation values and connector types. Similar parts in the family include the BW-S8W2 and BW-S50W2, offering alternative attenuation levels while maintaining similar frequency ranges and construction materials.
