Procurement Notes

Verify that the specific part number matches the required 13 dB attenuation value and SMA configuration. Confirm compliance with military specifications if applicable, as this series often adheres to strict quality standards. Ensure the operating environment temperature range aligns with system requirements before finalizing procurement orders.

Selection Notes

Select this model when a fixed 13 dB reduction is required in a 50 Ohm system. Consider the 2 W power rating against expected signal levels. Verify that the SMA interface compatibility matches existing circuit board or cable assemblies. Evaluate the 12.4 GHz upper frequency limit against operational bandwidth needs.

Part Context

This component belongs to the M3933/25 series of connectorized attenuators. It is designed for use in shielded environments requiring stable performance. The product line supports various attenuation values within the same form factor, allowing for standardized inventory management across different signal processing stages.

Replacement Considerations

Compatible substitutes include other M3933/25 series variants with matching SMA interfaces. Verify that alternative models maintain the 13 dB attenuation specification and 50 Ohm impedance. Ensure replacement parts meet the same frequency and power ratings for direct interchangeability.
