Procurement Notes

Verify the specific suffix W10 to confirm the module packaging configuration, as variations may exist within the product family. Confirm that the 20 dB attenuation specification aligns with the target circuit requirements. Ensure the operating environment remains within the specified -40°C to +85°C thermal limits. Check for end-of-life status or obsolescence notifications prior to finalizing procurement plans. Validate that the 50 Ohm impedance matches the surrounding network design.

Selection Notes

Select this component when a fixed 20 dB attenuation is required at frequencies approaching 50 GHz. Consider the 3.5 dB insertion loss budget when designing low-loss signal paths. Evaluate the 20 dBm power handling capability against peak signal levels in the application. Compare the module form factor against available board space constraints. Assess the need for wideband performance versus narrowband alternatives.
