ATT-0205-02-SMA-02

Attenuators Overview

The ATT-0205-02-SMA-02 is a fixed coaxial RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation of 2 dB with a frequency range extending from DC to 12.4 GHz. The device features SMA connectors and is rated for 2 Watts average power at 25°C, derating linearly to 0.5 Watts at 125°C. It exhibits a maximum Voltage Standing Wave Ratio (VSWR) of 1.07 and operates within a temperature range of -65°C to +125°C.

Attenuators Feature Summary

• Miniature package design offering precision performance in a small, lightweight form factor
• Temperature stable construction utilizing rugged stainless steel materials
• Fixed coaxial configuration ensuring consistent signal attenuation across the specified bandwidth

Attenuators Applications

• RF test and measurement equipment requiring precise signal level reduction
• Wireless communication systems operating within the microwave spectrum
• Signal conditioning modules in radar and electronic warfare applications

Attenuators Procurement Notes

Verify the specific attenuation value matches system requirements, as the ATT-0205 series includes variants with different dB ratings such as 9 dB or 6 dB. Confirm connector gender compatibility, as the series supports male/female combinations. Ensure environmental specifications meet operational needs, particularly regarding the high-temperature derating curve from 2W at 25°C to 0.5W at 125°C. Check RoHS compliance status if required by project standards.

Attenuators Selection Notes

Select this component when a fixed 2 dB attenuation is required up to 12.4 GHz. Consider the SMA inline module format for space-constrained designs. Evaluate power handling capabilities against peak and average signal levels, noting the linear derating behavior above 25°C. Compare VSWR specifications against system matching requirements to ensure minimal reflection losses in the transmission line.

Attenuators Part Context

This part belongs to the ATT-0205 series of miniature fixed coaxial attenuators. The series offers various attenuation values ranging from 2 dB to 60 dB and supports multiple connector configurations including male/male, female/female, and male/female combinations. These components are characterized by their rugged stainless steel construction and wide operating temperature range, suitable for demanding RF environments.

Attenuators Replacement Considerations

Direct substitutes include other ATT-0205 series variants with identical electrical parameters but different attenuation values, such as ATT-0205-06-SMA-02 or ATT-0205-09-SMA-02, provided the specific dB rating difference is acceptable. Cross-reference with Midwest Microwave's broader catalog for equivalent performance in alternative package styles.
