WA04P014XETL

Overview

The WA04P014XETL is a fixed RF attenuator from Walsin Technology Corporation, designed for wireless and radio frequency applications. It provides a nominal attenuation of 14 dB with a tolerance of +/-0.5 dB across a frequency range of 0 Hz to 3 GHz. The component features a 50 Ohm impedance and handles up to 100 mW of power. Constructed using ceramic technology, it utilizes a convex 0404 (1010 metric) surface-mount package.

Feature Summary

• Fixed 14 dB attenuation level for precise signal reduction
• Operates within a 0 Hz to 3 GHz frequency bandwidth
• Utilizes robust ceramic construction for thermal stability
• Designed for compact 0404 surface-mount integration

Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment calibration
• Mobile device circuitry
• Base station antenna interfaces

Procurement Notes

Verify the specific suffix 'ETL' against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure the requested quantity aligns with standard factory pack sizes. Confirm RoHS compliance status through current datasheets prior to final procurement decisions.

Selection Notes

Select this component when a fixed 14 dB reduction is required at 50 Ohms. The 100 mW power rating suits low-power RF paths. The 0404 footprint allows for dense PCB layouts. Verify that the 3 GHz upper frequency limit meets system requirements.

Part Context

This part belongs to the WA04P series of thin-film microwave attenuators. These components are engineered for high reliability in harsh environments. The series offers various attenuation values while maintaining consistent electrical performance across the specified frequency range.

Replacement Considerations

Check for direct substitutes within the WA04P series offering identical 14 dB attenuation and 0404 dimensions. Cross-reference impedance and power ratings to ensure compatibility with existing circuit designs.
