M3933/14-08S

Overview

The M3933/14-08S is a screened QPL RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a fixed attenuation of 4 dB with a frequency range of 0 Hz to 12.4 GHz. The component features SMA connectors and operates within a temperature range of -55°C to +125°C. It has a power rating of 2 W and an impedance of 50 Ohms.

Feature Summary

• Complies with MIL-DTL-M3933 specifications for military-grade reliability
• Features screened QPL status for qualified procurement listings
• Utilizes SMA connector interface for in-line module integration

Applications

• Military radar systems requiring precise signal attenuation
• Communication equipment operating within specified frequency bands
• Test and measurement instrumentation for RF signal conditioning

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact screening level and qualification status. Ensure compatibility with existing SMA interfaces and thermal management requirements for the intended operational environment. Cross-reference part numbers with current distributor catalogs to confirm availability and authenticity.

Selection Notes

Select this model when a fixed 4 dB attenuation is required within the 12.4 GHz bandwidth. Consider the 2 W power handling capability and wide temperature range for harsh environments. Verify that the SMA connector type matches the system's male or female port configuration before integration.

Part Context

This component belongs to the M3933 series of connectorized attenuators designed for high-reliability applications. The series offers various attenuation values while maintaining consistent electrical performance across the designated frequency ranges. It serves as a critical passive component in RF signal chains where precise power reduction is necessary.

Replacement Considerations

M3933/14-08N is a comparable variant within the same family offering identical electrical specifications but potentially differing in physical screening or packaging details. Verify mechanical dimensions and connector gender compatibility before substitution.
