Attenuators Procurement Notes

This component is scheduled for obsolescence and will be discontinued by the manufacturer. Procurement should be verified against current availability status before integration into new designs. Existing stock may be limited, and lead times are subject to change. Engineers must confirm end-of-life timelines with authorized distributors to avoid supply chain disruptions during production phases.

Attenuators Selection Notes

Select this component when a 2 dB fixed attenuation value is required in high-frequency circuits up to 40 GHz. It is suitable for applications needing precise signal level adjustment with minimal reflection due to its high return loss. Consider the 1 W power rating and extended temperature range for harsh environment deployments. Verify compatibility with existing 50 Ω system impedance requirements.
