ATT-0444-19-SMA-02

Attenuators Overview

The ATT-0444-19-SMA-02 is a connectorized RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a fixed attenuation value of 19 dB across a frequency range from DC to 18 GHz. The device features SMA connectors and supports a power rating of 2 W. It is designed as a male/female module for interconnect applications.

Attenuators Feature Summary

• Provides fixed 19 dB attenuation
• Operates from DC to 18 GHz
• Features SMA connector interface
• Supports 2 W power handling

Attenuators Applications

• Broadband microwave signal conditioning
• RF test and measurement setups
• Signal level adjustment in communication systems

Attenuators Procurement Notes

Verify the specific datasheet version for precise VSWR and return loss specifications, as these parameters can vary between manufacturing batches. Confirm that the SMA connector gender configuration matches the system requirements, as the product description indicates male/female compatibility but exact pinout details should be checked against the official drawing. Ensure the operating environment remains within the specified thermal limits for continuous 2 W dissipation.

Attenuators Selection Notes

Select this component when a fixed 19 dB reduction is required at frequencies up to 18 GHz. Compare with other models in the ATT-0444 series for different attenuation values such as 14 dB or 16 dB if the signal level needs differ. Consider the SMA interface compatibility with existing cabling infrastructure. Evaluate the 2 W power rating against peak and average signal levels to prevent damage.

Attenuators Part Context

This part belongs to the ATT-0444 series of connectorized attenuators from Midwest Microwave. The series offers various fixed attenuation values including 8 dB, 14 dB, and 19 dB options. All models share similar form factors and SMA connectivity, allowing for modular integration into RF chains. The series is designed for broadband performance up to 18 GHz.

Attenuators Replacement Considerations

Direct substitutes include ATT-0444-14-SMA-02 and ATT-0444-16-SMA-02 from the same manufacturer. These parts offer different attenuation values (14 dB and 16 dB respectively) while maintaining identical frequency ranges and connector types. Verify that the system can tolerate the difference in signal loss before swapping.
