Attenuators Procurement Notes

Verify the obsolete status and end-of-life notifications prior to procurement. Confirm that alternative components are available for long-term production support. Ensure compliance with RoHS directives and check for specific environmental certifications required by your supply chain standards. Validate package markings against official datasheets to prevent counterfeit risks.

Attenuators Selection Notes

Select this component when a fixed 32 dB attenuation step is required within the 300 kHz to 2.5 GHz range. Consider the 1W power handling capability for high-power RF paths. Evaluate the GaAs technology benefits regarding linearity and noise figure compared to silicon alternatives. Ensure the 50 Ohm impedance matches the surrounding circuit design requirements.

Attenuators Part Context

This part belongs to Skyworks' portfolio of RF attenuators and signal conditioning devices. It complements other digital and analog attenuators in their lineup, offering a specific discrete attenuation step. The GaAs construction distinguishes it from lower-frequency silicon-based solutions, targeting applications demanding higher frequency stability and power handling.

Attenuators Replacement Considerations
