Attenuators Procurement Notes

Verify the specific datasheet version for the ATT-0290-09-HEX-02 to confirm current manufacturing status and compliance details. Ensure that the required SMA connector gender and HEX module dimensions match your system integration constraints. Cross-reference the 2W power rating against your peak and average power requirements to prevent component failure. Confirm environmental specifications align with your operational temperature extremes before finalizing procurement.

Attenuators Selection Notes

Select this model when a fixed 9 dB attenuation is required up to 18 GHz. The HEX package offers a compact form factor suitable for dense circuit layouts. Consider the 2W power handling capability for high-signal environments. Verify compatibility with SMA interfaces and ensure the -65°C to +125°C operating range meets your thermal design requirements compared to lower-grade commercial alternatives.

Attenuators Part Context

This component belongs to the ATT-0290 series of connectorized attenuators from Midwest Microwave. The series is designed for high-performance RF applications requiring stable attenuation values over broad bandwidths. The HEX packaging variant provides enhanced mechanical durability compared to standard bulk modules, making it suitable for ruggedized electronic assemblies and professional test equipment.

Attenuators Replacement Considerations

Direct substitutes include other ATT-0290 series variants with different attenuation values, such as ATT-0290-03-HEX-02 or ATT-0290-06-HEX-02, provided the attenuation difference is acceptable. For non-Hex packaging, check ATT-0290-09-SMA-02 if module form factor is not critical. Always verify electrical parameters and mechanical dimensions before substitution.
