Attenuators Procurement Notes

Verify the manufacturer part number ATT-0290-07-SMA-02 against official Cinch Connectivity Solutions documentation to ensure authenticity. Confirm that the SMA connector gender matches the Male/Female configuration specified in the datasheet. Check compliance with RoHS and REACH standards if required for your specific application environment. Ensure the operating temperature range meets your system's thermal requirements.

Attenuators Selection Notes

Select this component when a precise 7 dB reduction is needed within an 18 GHz bandwidth. The SMA interface ensures compatibility with standard coaxial test equipment and RF modules. Consider the 2W power rating for linear operation without thermal degradation. The wide temperature range allows deployment in harsh environments where standard commercial components might fail.

Attenuators Part Context

This model belongs to the ATT-0290 series of connectorized attenuators manufactured by Midwest Microwave, a brand under Cinch Connectivity Solutions. The series offers various attenuation values and connector types, designed for high-performance RF applications requiring stable impedance and low VSWR across broad frequency bands.

Attenuators Replacement Considerations

Direct substitutes include ATT-0290-07-HEX-02 (Hex connector variant) or ATT-0290-09-SMA-02 (9dB value). Verify connector gender and physical dimensions before substitution to ensure mechanical fit in existing assemblies.
