WA04P019XGTL

Overview

The WA04P019XGTL is a fixed RF attenuator manufactured by Walsin Technology Corporation. It provides an attenuation value of 19 dB with a maximum operating frequency of 3 GHz. The component features a 50 Ohm impedance and a power rating of 100 mW. It utilizes silicon technology and is housed in a 0404 (1010 Metric) convex surface-mount package. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Fixed 19 dB attenuation for signal level control
• Silicon-based construction for compact integration
• Convex 0404 surface-mount footprint

Applications

• RF signal path conditioning
• Test and measurement equipment
• Wireless communication modules

Procurement Notes

Verify the specific suffix 'GTL' against official Walsin documentation to confirm packaging and tape specifications. Ensure the silicon technology variant matches design requirements, as ceramic alternatives exist within the series. Confirm RoHS compliance status through current datasheets before finalizing procurement orders.

Selection Notes

Select this component when a precise 19 dB reduction is required at frequencies up to 3 GHz. The 100 mW power handling capability suits low-power RF applications. The 0404 convex package allows for standard SMT assembly processes. Verify impedance matching and thermal management needs for the target circuit environment.

Part Context

This part belongs to the WA04P series of chip attenuators from Walsin. The series includes various attenuation values such as 4 dB, 7 dB, 12 dB, 13 dB, 17 dB, and 18 dB. These components are designed for wireless and RF integrated circuits, offering consistent performance across the specified frequency range.

Replacement Considerations

Other WA04P series parts like WA04P017XGTL or WA04P018XGTL offer similar form factors but different attenuation values. Cross-referencing datasheets is necessary to ensure electrical compatibility if substituting with other manufacturers' silicon attenuators.
