Attenuators Procurement Notes

Verify the specific part number ATT-0298-04-SMA-02 against official Cinch Connectivity Solutions documentation to ensure compatibility with system requirements. Confirm connector gender and frequency specifications match application needs. Check for RoHS compliance status if required by regulatory standards. Ensure thermal management aligns with the specified operating temperature range during installation.

Attenuators Selection Notes

Select this component when a fixed 4 dB attenuation is required at frequencies up to 26.5 GHz. Consider the 2 W power rating for signal strength limitations. The SMA interface dictates connector compatibility with existing PCB or cable assemblies. Evaluate the wide temperature range for environmental suitability in harsh conditions compared to standard commercial grade parts.

Attenuators Part Context

This part belongs to the ATT-02 series of fixed attenuators from Midwest Microwave. It shares design characteristics with other variants like ATT-0298-09-SMA-02 but differs in attenuation value. The series is known for broadband performance and robust construction. It serves as a passive component for signal conditioning in RF paths.

Attenuators Replacement Considerations

Direct substitutes may include ATT-0298-09-SMA-02 for different attenuation needs, though values differ. Verify pinout and mechanical dimensions before swapping. No identical functional replacements are publicly confirmed; check manufacturer cross-reference lists for exact matches.
