Attenuators Procurement Notes

Verify the specific manufacturer part number against official Cinch Connectivity Solutions documentation to ensure authenticity. Confirm that the 2.92mm connector orientation matches your system requirements. Check current supply chain status as availability may vary. Ensure environmental specifications meet operational needs. Cross-reference datasheet parameters for critical design integration.

Attenuators Selection Notes

Select this model when a precise 3 dB reduction is required at frequencies approaching 40 GHz. The 2.92mm interface offers superior performance over SMA or V-type connectors in this range. Consider the 1W power limit for thermal management. Evaluate physical dimensions against available space. Compare against other series if different attenuation values or connector types are needed.

Attenuators Part Context

This component belongs to the ATT-0640 series of fixed attenuators from Midwest Microwave. The series includes various attenuation values such as 10 dB and 20 dB options. These modules are designed for high-reliability applications in aerospace and defense sectors. The 2.92mm connector type ensures low VSWR and consistent impedance matching across the wide bandwidth.

Attenuators Replacement Considerations

Public confirmed substitute part numbers include ATT-0640-10-29M-02 for 10 dB attenuation and ATT-0640-20-29M-02 for 20 dB attenuation within the same series. Other variants like ATT-0640-03-HEX-02 offer similar electrical performance but utilize Hexagonal connectors instead of 2.92mm interfaces.
