Procurement Notes

Verify the specific datasheet version for the M3933/25-34N to confirm mechanical dimensions and material composition. Ensure that the 50-ohm impedance and 8-dB attenuation values align with system requirements. Check for any specific handling instructions related to the non-screened construction and bulk packaging format before integration.

Selection Notes

Select this component when a fixed 8-dB reduction is required in an 18-GHz SMA-based system. Consider the 2-watt power handling limit and the wide temperature range for harsh environment applications. Compare against screened variants if electromagnetic interference shielding is necessary for the specific deployment scenario.
