ATT-0290-07-HEX-02

Attenuators Overview

The ATT-0290-07-HEX-02 is a fixed RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides a nominal attenuation of 7 dB with a tolerance of 0.5 dB across a frequency range of DC to 18 GHz. The device features SMA male-to-female connectors and supports a maximum power rating of 2 W. It operates within a temperature range of -65°C to +125°C. The unit utilizes a HEX single-row module package, measuring 21.8 mm in length and weighing approximately 18.49 g.

Attenuators Feature Summary

• Provides precise 7 dB signal attenuation with tight 0.5 dB tolerance for high-frequency applications up to 18 GHz
• Features robust SMA male-to-female interconnects ensuring reliable signal transmission in demanding environments
• Designed with a wide operational temperature range from -65°C to +125°C for extreme condition stability

Attenuators Applications

• High-frequency test and measurement instrumentation requiring stable attenuation
• Wireless communication systems operating within the DC to 18 GHz spectrum
• Defense and aerospace electronic subsystems necessitating wide temperature tolerance

Attenuators Procurement Notes

Verify the specific manufacturer part number against official Cinch Connectivity Solutions documentation to ensure authenticity. Confirm that the SMA connector gender configuration matches the system requirements. Check for RoHS compliance status and REACH SVHC declarations as required by project specifications. Ensure the ordering suffix corresponds to the exact HEX module variant intended for the application.

Attenuators Selection Notes

Select this component when a fixed 7 dB attenuation is required at frequencies extending to 18 GHz. The SMA interface is suitable for standard coaxial setups. Consider the 2 W power handling capability relative to the system's maximum output power. The wide temperature range makes it appropriate for harsh environmental deployments where standard commercial parts may fail.

Attenuators Part Context

This model belongs to the ATT-0290 series of connectorized attenuators from Midwest Microwave. The series offers various attenuation values and connector types, including SMA and HEX modules. The ATT-0290 designation specifically indicates the 18 GHz frequency range capability, distinguishing it from lower-frequency variants like the ATT-0292 series which is limited to 8 GHz.

Attenuators Replacement Considerations

Direct substitutes include other models within the ATT-0290 series with identical 7 dB attenuation and SMA connectors, such as ATT-0290-07-SMA-02 if connector orientation permits. Verify mechanical dimensions and electrical tolerances before swapping between different package styles or manufacturers.
