WA04P002XBTL

Overview

The WA04P002XBTL is a surface-mount RF attenuator manufactured by Walsin Technology Corporation. It provides a nominal attenuation of 2 dB with a tolerance of +/-0.3 dB. The device operates within a frequency range of 0 Hz to 3 GHz and maintains a 50 Ohm impedance. Key electrical specifications include a maximum Voltage Standing Wave Ratio (VSWR) of 1.2 and a power handling capacity of 100 mW. It is housed in a compact 0404 (1010 metric) convex package, suitable for wireless and RF integrated circuit applications.

Feature Summary

• Provides precise signal level reduction in RF and microwave circuits
• Maintains low reflection characteristics with a maximum VSWR of 1.2
• Designed for high-frequency operation up to 3 GHz
• Utilizes a compact surface-mount package for space-constrained designs

Applications

• Signal level adjustment in RF transmission lines
• Impedance matching networks in wireless communication systems
• Test and measurement equipment requiring fixed attenuation
• RF front-end modules in mobile devices

Procurement Notes

Verify the specific suffix 'XBTL' against the manufacturer's official datasheet to confirm packaging type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements as stated in the product documentation. Cross-reference the Mouser or DigiKey part numbers with the original manufacturer data to validate authenticity and technical parameters before procurement.

Selection Notes

Select this component when a fixed 2 dB attenuation is required at frequencies up to 3 GHz. The 50 Ohm impedance matches standard RF systems. Consider the 100 mW power rating and 0404 package size for thermal and spatial constraints. Verify that the +/-0.3 dB tolerance aligns with system accuracy requirements.

Part Context

This component belongs to the WA04P series of chip attenuators from Walsin Technology Corporation. These devices are ceramic-based passive components designed for wireless and RF applications.
