WA04P003XBTL

Overview

The WA04P003XBTL is a fixed RF attenuator manufactured by Walsin Technology Corporation. It provides a nominal attenuation of 3 dB with an impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 3 GHz and supports a maximum power handling of 100 mW. Key electrical specifications include a maximum VSWR of 1.2 and a signal level of 16.02 dBm. The component utilizes ceramic technology and is available in a 0404 (1010 Metric) surface mount package, which is described as both concave and convex in various documentation. It functions as a single-channel passive component.

Feature Summary

• Provides precise 3 dB signal attenuation for RF applications
• Operates effectively across a wide frequency spectrum up to 3 GHz
• Constructed using durable ceramic materials for stability
• Designed for surface mount integration in compact circuits

Applications

• RF signal conditioning in wireless communication systems
• Impedance matching networks requiring specific loss values
• Test and measurement equipment signal path management
• Mobile device front-end module protection

Procurement Notes

Verify the specific package variant, as documentation references both concave and convex configurations for the 0404 footprint. Confirm RoHS compliance status through official manufacturer channels prior to ordering. Ensure the selected supplier provides valid traceability documents. Cross-reference the datasheet version to confirm the exact electrical tolerances and thermal characteristics match the design requirements. Validate that the 100 mW power rating is sufficient for the intended application environment.

Selection Notes

Select this component when a fixed 3 dB loss is required at 50 Ohms within the 3 GHz bandwidth. Consider the 100 mW power limit and 16.02 dBm signal level constraints during circuit design. Evaluate the 0404 package dimensions against PCB space limitations. Compare the 1.2 VSWR specification against system return loss requirements. Assess the -40 C to +125 C operating temperature range against environmental conditions.

Part Context

This part belongs to the WA04P series of RF attenuators from Walsin Technology Corporation. The series offers various attenuation values while maintaining consistent 50 Ohm impedance and 0404 packaging. These components are designed for high-frequency applications where stable performance and low profile are critical. The WA04P series supports both tape and reel and cut tape packaging options for flexible manufacturing integration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs by matching the 3 dB attenuation, 50 Ohm impedance, and 0404 package dimensions. Check if alternative manufacturers offer equivalent ceramic-based attenuators with similar VSWR and power handling specifications.
