• Harsh environment RF signal conditioning

Procurement Notes

Verify current availability directly with the manufacturer or authorized distributors, as this item is often produced to order. Confirm specific screening requirements such as QPL status if mandated by your program documentation. Ensure that the SMA gender configuration matches your system interconnect needs before finalizing procurement orders.

Selection Notes

Select this model when a 24.5 dB attenuation value is required within the 18 GHz bandwidth. Consider the 2 W power handling capability for high-power applications. Verify environmental compliance and screening levels against project specifications. Ensure SMA compatibility with existing cable assemblies and test fixtures.

Part Context

This part belongs to the M3933/16 series of connectorized attenuators from Midwest Microwave. These components are designed for military and aerospace applications requiring high reliability. The series offers various attenuation values while maintaining consistent electrical performance across the specified frequency range.

Replacement Considerations

Check for direct cross-reference part numbers from other manufacturers offering equivalent SMA attenuators with 24.5 dB attenuation and 18 GHz bandwidth. Verify mechanical dimensions and pinout compatibility if substituting with non-Mil-spec equivalents.
