Procurement Notes

Verify the specific attenuation value associated with the suffix '30' against the official manufacturer datasheet, as generic listings may not specify the exact dB loss. Confirm that the stainless steel housing meets environmental requirements. Ensure the SMA gender configuration matches the system design needs before procurement.

Selection Notes

Select this component when a military-grade SMA attenuator is required for high-frequency applications up to 18 GHz. Consider the 2 W power rating and 50 Ohm impedance for compatibility with standard RF systems. Verify the specific attenuation value needed for the circuit design against the manufacturer's detailed specifications.

Part Context

This model belongs to the M3933 series of RF fixed attenuators by Amphenol SV Microwave. These components are designed to meet rigorous military standards, ensuring reliability in demanding conditions.
