WA04P008XCTL

Overview

The WA04P008XCTL is a surface-mount RF attenuator manufactured by Walsin Technology Corporation. It provides a nominal attenuation of 8 dB with a tolerance of +/-0.4 dB. The device operates within a frequency range of 0 Hz to 3 GHz and features a characteristic impedance of 50 Ohms. It has a maximum Voltage Standing Wave Ratio (VSWR) of 1.2 and handles up to 100 mW of power. The component is housed in a 0404 (1010 metric) convex package, suitable for automated surface mount assembly.

Feature Summary

• Provides precise 8 dB signal attenuation for RF circuitry
• Operates effectively across a wide bandwidth from DC to 3 GHz
• Maintains low VSWR for minimal signal reflection
• Constructed using ceramic technology for thermal stability

Applications

• RF signal level adjustment in wireless communication systems
• Impedance matching networks in 50-Ohm transmission lines
• Test and measurement equipment signal conditioning
• Mobile device front-end module protection

Procurement Notes

Verify the specific suffix 'CTL' corresponds to the required tape and reel or cut tape packaging configuration as defined by the manufacturer's standard packing methods. Confirm RoHS compliance status and MSL rating against current project requirements before finalizing procurement orders to ensure supply chain compatibility.

Selection Notes

Select this component when an 8 dB fixed attenuation value is required at 50 Ohms impedance. Ensure the operating environment stays within the specified temperature range and that the 100 mW power handling capacity meets the system's peak signal levels. Compare VSWR specifications against other series variants if strict return loss performance is critical.

Part Context

This part belongs to the WA04P series of chip RF attenuators from Walsin Technology Corporation. These components are designed for high-frequency applications requiring stable attenuation values. The series utilizes thin-film or ceramic technologies to achieve consistent performance across the microwave spectrum, serving as passive linear devices in RF signal paths.

Replacement Considerations

Compatible substitutes include other 8 dB, 50 Ohm, 0404 package attenuators from manufacturers such as Skyworks or Qorvo. Verify that replacement parts match the 3 GHz frequency limit, 100 mW power rating, and physical footprint dimensions to ensure board-level interchangeability without redesign.
