Procurement Notes

Verify that the specific order includes the 'S' suffix designation, which indicates the component is screened according to MIL-DTL-M3933 requirements. Confirm compatibility with existing SMA interfaces and ensure the 2 W power rating meets system thermal constraints. Check for RoHS non-compliance status if environmental regulations apply to the final assembly. Validate manufacturer documentation against current revision standards before procurement.

Selection Notes

Select this model when a fixed 6 dB attenuation is required within the DC to 12.4 GHz range. Ensure the application supports SMA connector types and 50 Ohm impedance matching. Consider the 2 W power handling capability relative to peak and average signal levels. Verify that military screening specifications are necessary for the intended deployment environment compared to commercial alternatives.
