Procurement Notes

Verify the specific suffix 'N' against official Amphenol documentation to confirm material composition and plating specifications. Ensure the required attenuation tolerance matches the standard datasheet values. Confirm that the SMA gender orientation aligns with the system interconnect requirements before finalizing procurement orders.

Selection Notes

Select this model when a fixed 7 dB reduction is required in the 18 GHz bandwidth. Consider the 2W power limit for thermal management in high-power chains. Evaluate the SMA interface compatibility with existing board layouts. Compare against screened variants if environmental sealing is necessary for the deployment scenario.
