Procurement Notes

Verify that the specific suffix 'N' corresponds to the required material or plating configuration as defined in the official datasheet, as ordering suffixes may indicate variations in construction or certification. Confirm compliance with current export control classifications (EAR99) and ensure the non-RoHS status aligns with project regulatory requirements before finalizing procurement orders.

Selection Notes

Select this model when a fixed 2dB attenuation is required within the 12.4 GHz bandwidth. Ensure the system impedance matches the component's design, typically 50 Ohms for this series. Consider the SMA connector type for compatibility with existing test fixtures or cable assemblies. Verify power handling capabilities against peak signal levels to prevent damage during operation.

Part Context
