WA04P018XGTL

Overview

The WA04P018XGTL is an RF attenuator from Walsin Technology Corporation, designed for signal level reduction in wireless applications. It provides a fixed attenuation of 18 dB with a nominal impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 3 GHz and supports a power rating of 100 mW. Manufactured using ceramic technology, it features a convex surface mount package in the 0404 (1010 Metric) dimension. The component complies with RoHS3 standards and is classified under EAR99.

Feature Summary

• Fixed 18 dB attenuation value for precise signal control
• Operates up to 3 GHz frequency range
• Ceramic construction for thermal stability
• Surface mount design in 0404 convex package

Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment requiring fixed attenuation
• Mobile device front-end circuitry
• Base station antenna distribution networks

Procurement Notes

Verify the specific suffix GTL against official Walsin documentation to confirm packaging and tolerance specifications. Ensure the procurement channel provides valid traceability for ceramic RF components. Cross-reference the 0404 footprint requirements with PCB layout guidelines before ordering. Confirm RoHS3 compliance status through current manufacturer declarations rather than distributor summaries.

Selection Notes

Select this component when a fixed 18 dB loss is required within a 50 Ohm system operating below 3 GHz. The ceramic construction suits environments needing stable performance without active tuning. Consider the 100 mW power limit for high-power RF paths. The convex package profile may influence solder joint formation compared to flat variants.

Part Context

This part belongs to the WA04P series of chip attenuators from Walsin Technology Corporation. The series utilizes ceramic substrates for high-frequency stability. Similar parts in the family include WA04P004XBTL and WA04P012XDTL, which offer different attenuation values but share the same 0404 form factor and 50 Ohm impedance characteristics.
