WA04PR15XBTL

Overview

The WA04PR15XBTL is a surface-mount RF attenuator manufactured by Walsin Technology Corporation. It provides a nominal attenuation of 1.5 dB with a 50 Ohm impedance. The device operates from 0 Hz to 3 GHz and features a maximum VSWR of 1.2. It utilizes silicon technology in a 0404 (1010 metric) convex package. The component supports an operating temperature range from -40°C to +125°C and has a power rating of 100 mW.

Feature Summary

• Provides precise 1.5 dB signal attenuation for RF circuits
• Operates across a wide frequency range up to 3 GHz
• Maintains low voltage standing wave ratio for signal integrity
• Designed for high-temperature reliability in compact packages

Applications

• RF signal level adjustment in wireless communication systems
• Impedance matching networks in microwave circuits
• Signal conditioning in test and measurement equipment
• Attenuation stages in radar and satellite communication modules

Procurement Notes

Verify the specific suffix 'XBTL' against the manufacturer's latest datasheet to confirm packaging details and tape-and-reel specifications. Ensure the procurement channel provides traceability documentation compliant with RoHS standards. Confirm that the 0404 package dimensions match the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a fixed 1.5 dB attenuation is required within a 50 Ohm system. Consider the 100 mW power handling limit for signal strength constraints. The 0404 package size suits space-constrained designs. Verify thermal management capabilities given the +125°C maximum operating temperature specification.
