M3933/25-80S

Overview

The M3933/25-80S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides an attenuation value of 12 dB within a frequency range of 0 Hz to 18 GHz. The component features SMA connectors and operates at a characteristic impedance of 50 Ohms with a maximum power rating of 2 Watts. Designed as an in-line module, it complies with MIL-DTL-M3933 standards for military-grade applications.

Feature Summary

• Provides precise 12 dB signal attenuation across a wide bandwidth up to 18 GHz
• Constructed with SMA connectors for reliable high-frequency interconnection
• Complies with MIL-DTL-M3933 specifications for ruggedized performance
• Supports continuous wave power handling up to 2 Watts

Applications

• Military communication systems requiring standardized attenuation
• Test and measurement equipment calibration setups
• Radar system signal conditioning modules
• Avionics RF signal path management

Procurement Notes

Verify the specific suffix 'S' against official manufacturer documentation to confirm connector gender and screening level, as variations exist within the M3933/25 series. Ensure compliance with MIL-DTL-M3933 requirements for your application environment. Confirm RoHS status and material composition details directly from the datasheet prior to integration.

Selection Notes

Select this model when a fixed 12 dB attenuation is required at frequencies extending to 18 GHz. The SMA interface suits standard coaxial test fixtures. Consider thermal management capabilities given the 2W power rating. Validate that the military-grade specification aligns with the operational temperature and reliability needs of the target system.

Part Context

This component belongs to the M3933/25 series of fixed attenuators produced by Midwest Microwave under the Cinch Connectivity Solutions brand. The series offers various attenuation values and frequency ranges tailored for defense and aerospace sectors. The M3933/25-80S specifically addresses mid-range attenuation needs in high-frequency microwave applications.

Replacement Considerations

Compatible substitutes include other MIL-DTL-M3933 compliant attenuators with matching 12 dB attenuation and 18 GHz bandwidth. Verify exact connector gender (male/female configuration) and physical dimensions to ensure mechanical fit. Cross-reference part numbers such as M3933/25-xxN or xxS variants from the same manufacturer family.
