ATT-0275-03-SMA-02

Attenuators Overview

The ATT-0275-03-SMA-02 is a fixed attenuator from the ATT-0275 series manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation of 3 dB with a frequency range extending from DC to 18 GHz. The device features SMA connectors and supports a maximum power rating of 2 W. It operates within a temperature range of -65°C to +125°C. This component is classified as a connectorized attenuator designed for high-frequency signal management.

Attenuators Feature Summary

• Provides fixed 3 dB attenuation across a wide bandwidth up to 18 GHz
• Utilizes SMA male/female interface for reliable RF connections
• Rated for 2 W power handling in inline module configuration
• Operates reliably in extreme temperatures from -65°C to +125°C

Attenuators Applications

• RF test and measurement equipment
• Telecommunications infrastructure
• Aerospace and defense systems
• Microwave circuit design

Attenuators Procurement Notes

Verify the specific datasheet version for the ATT-0275-03-SMA-02 to confirm current manufacturing status and detailed electrical tolerances. Ensure compatibility with SMA mating connectors and check thermal management requirements for the 2 W power rating in the intended application environment. Confirm RoHS compliance details if required for the project specifications.

Attenuators Selection Notes

Select this model when a precise 3 dB reduction is needed at frequencies up to 18 GHz. The SMA interface offers broad availability and standard compatibility. Consider the 2 W power limit and wide operating temperature range for harsh environments. Compare against other series like ATT-0290 or ATT-0523 if different attenuation values or frequency ranges are required.

Attenuators Part Context

This part belongs to the ATT-0275 series of connectorized attenuators. It shares the same SMA interface and general form factor with related models such as the ATT-0276-03-SMA-02, though frequency ranges may differ. The series is designed for consistent performance in microwave applications requiring stable attenuation characteristics.

Attenuators Replacement Considerations

Direct substitutes include ATT-0276-03-SMA-02 for similar attenuation but potentially different frequency limits. For higher frequency operation up to 18 GHz with different attenuation, consider ATT-0290-07-SMA-02 or ATT-0523-07-SMA-02. Verify mechanical dimensions and connector gender before substitution.
