Procurement Notes

Verify the specific screening requirements against your system's environmental standards before procurement. Confirm that the SMA female-to-male orientation matches your interconnect needs. Ensure the 2 W power rating aligns with your peak signal levels. Check for any updated datasheet revisions that may affect mechanical dimensions or material specifications. Validate compatibility with existing cable assemblies and mounting hardware.

Selection Notes

Select this model when a fixed 10 dB attenuation is required in an SMA interface. Consider the 18 GHz bandwidth limit for high-frequency designs. Evaluate the 2 W power handling capability against your system's output levels. The screened design suits harsh environments where shielding is critical. Compare with other M3933 series variants if different attenuation values are needed.
